When Primary Arms began selling red dot sights over a decade ago, our mission was simple: to offer the best quality optics to our customers at the best possible prices and back them up with outstanding customer service. That mission has never wavered. The result of that mission for you, our valued customer, is unmatched value for your dollar. That value has made Primary Arms one of the fastest growing optics manufacturers in the world. We love what we do, but truth be told, we do it all for you. Bringing you the best in quality and value is what drives us, and when we make something you love, we’ve accomplished our mission.

    We’ve come a long way from those early days selling red dots. In the years since, we’ve added a complete lineup of riflescopes, prism scopes, and more to our brand of optics and we are proud to offer free shipping on your entire order when you purchase any Primary Arms optics including scopes red dot sights or red dot magnifiers from primaryarms.com. Many of the fan favorite scopes are built around the ACSS reticle system, which helps our optics outpace the competition in many practical and tactical shooting applications. We listen to the needs and wants of our customers who shoot with our scopes and we continually innovate to make the products you love even better. We want to shine the spotlight on a handful of our most popular products, each backed by loyal and vocal fans like you that truly believe in the power and precision of Primary Arms Optics.


    Low power variable optics (LPVOs) are some of the most popular scopes on the market today. Fast and accurate at low power, this style of scope can give you target acquisition speeds akin to red dot sights. At high power, you get enough magnification and visibility to engage targets out to 800 yards or more. Our most popular low power variable optics come from our Silver Series of scopes, the heart of our lineup. They are the 1-6x24mm First Focal Plane (FFP) scope, 1-6x24mm Second Focal Plane (SFP) scope, and the 1-8x24mm Second Focal Plane scope.

    A large part of what has made these scopes so popular with our customers is the ACSS reticles with which they are equipped. The 1-6x SFP and the 1-8x SFP scopes feature the ACSS 5.56/5.45/.308 Reticle and they are packed with the advanced features that have made ACSS one of the most popular reticle systems on the market. The ACSS reticle’s innovative and intuitive design gives you the ability to range targets at unknown distances and get an accurate bullet-drop-compensating holdover point of aim out to 800 yards without the need to adjust your turrets at all. The reticle also provides moving target leads to take more accurate shots when your target is on the move. Wind holds help you to easily compensate for crosswinds and achieve hits when weather conditions are less than ideal. The heart of the reticle is a bold horseshoe surrounding a center chevron tip. The chevron is more precise than traditional crosshairs because the tip provides an infinitely small point of aim that never obstructs your view of the target. The bold horseshoe naturally draws your eye and gets you on target for quick snap shooting.

    The SLx6 1-6×24 FFP scope features the ACSS Raptor Reticle and it was one of the most anticipated optics releases we’ve had so far. Taking full advantage of the first focal plane design, the Raptor reticle is an optimized version of the ACSS system, designed to be fast to acquire at low power, while still maintaining all the advanced features of other ACSS reticles at higher magnification. The same bold horseshoe and center chevron make up the heart of the Raptor reticle, but instead of being a small, central portion of the system, the horseshoe encapsulates the entire reticle. This allows for a sight picture and acquisition speed like a red dot or holosight when the magnification is set to 1x power. The wide field of view, clear glass, and FFP-optimized reticle combine to make one of the most capable LPVOs on the market.

    Being able to quickly go from red-dot-like speed at 1x magnification to 6- or 8-power magnification for precision in one optic is what people love about LPVOs. For these popular scope models highlighted here, as well as nearly 20 others we offer, our engineers have developed a custom magnification throw lever that interfaces with the magnification ring’s integral “fin” and enhances your ability to transition from 1x power to the maximum magnification setting with speed and ease. We call it the Mag-TightTM Throw Lever. It’s machined from 6061-T6 aluminum, Type III hardcoat anodized, and comes with a limited lifetime warranty. Never worry about finding a magnification lever that fits your favorite Primary Arms LVPO ever again – we’ve made you a custom solution.


    We built our name and reputation on red dot sights. These Primary Arms red dots are optics you can count on, proven by hundreds of torture tests and customer reviews. The Silver Series Advanced Micro Dots, available in models with either rotary knob (MD-RB-AD) or push-button (MD-ADS) illumination control, are each top-sellers and are packed incredible value. They feature 50,000 hours of illumination at medium brightness settings and they are daylight bright at the highest setting. They are nitrogen purged, waterproof, and shockproof, so you can trust them to perform for years to come.


    Prism scopes offer many advantages. The fixed magnification gives you a consistent sight picture and the ease of operation is preferable for many shooting applications. Additionally, prism scopes are one of the most compact and lightweight optic solutions for your rifle. They’re generally more robust and rugged for shooters who want to run their rifles hard and know their optic will hold up, such as on a duty rifle or in a tactical application. Prism scopes feature reticles etched into glass, so even if your battery were to fail or if the illumination is turned off, a high-contrast black reticle is always there – crisp, clear, and ready to perform.

    Primary Arms has prism scopes with many magnification settings to choose from. The SLx Compact 1×20 Prism Scope with ACSS Cyclops Reticle (PAC1X-ACSS-CYCLOPS) was another highly anticipated release from Primary Arms. For shooters who want the speed and large field of view of a red dot sight but have an astigmatism or other eye issues that make red dot sights imprecise and hard to use, the etched reticle and 1x power make this prism scope an ideal choice. The ACSS Cyclops Reticle is simple yet retains advanced features that can be found in all the other ACSS reticles. With a dual-purpose ranging ladder that allows for vertical or horizontal target ranging out to 400 yards, the familiar CQB horseshoe, and the ultra-precise chevron center, this 1x power prism scope is more versatile than a red dot sight while retaining the speed and a large field of view. The 1×20 Prism Scope is protected by a lifetime warranty, so if anything were to ever happen to the optic, you can have confidence knowing our in-house customer service team will be there to resolve your issue.

    The Primary Arms SLx Compact 2.5×32 Prism Scope with ACSS-CQB-M1 Reticle (PAC2.5X) gives you the ideal amount of magnification for medium range engagement. The outer horseshoe incorporates ranging ladders that can be used vertically or horizontally to range estimate a target’s distance afield. The inner horseshoe serves as a CQB point of aim to get on target quickly, accompanied by an inner dot for more precise shots. Bullet drop compensation is built in below the center dot and is compatible with many different types of ammunition to take fast and accurate shots out to 600 yards.

    Stepping up in magnification to the SLx Gen II 3×32 Compact Prism Scope with ACSS-5.56-CQB-M2 Reticle (PAC3X-GENII-ACSS-5.56) gives you even more capability to reach out and record hits at long range. The CQB M2 variant of this ACSS reticle retains all the features found in the M1 version but it adds another method of ranging built into the bullet drop compensation below the center point of aim. Horizontal bars across the BDC ladder correlate to an 18-inch wide target at the given distance. Beside each ranging bar, holdover dots give you the ability to adjust for crosswind at that distance and achieve a higher first-hit probability in suboptimal weather conditions. If you’re the kind of shooter who wants the best capability in all circumstances, the Gen II 3x prism scope features a removable section of Picatinny rail on the top of the body, so you can add a mini reflex sight for CQB and still use the prism scope for shooting at distance – an all-in-one solution on your rifle. The Gen II 3x prism also carries our lifetime warranty.

    All our prism scopes feature removable bases, so whatever your mounting needs or preferences are, for an AR-15AK-47, or even rifles with carry handles, you can make use of these powerful scopes. All are built tough, shockproof, waterproof and fog resistant with super clear glass and forgiving eye boxes to accommodate shooters of all styles and body types.

    In 2016 We teamed up with Trijicon to bring you the revered ACOG prism scope combined with our Advanced Combat Sighting System (ACSS). Just three years later we are doing it again, only this time we developed a new reticle designed specifically for use in the ACOG. Our new ACSS Aurora reticle has been modified to align with the philosophy of use that Trijicon set forth to accomplish with the ACOG. We believe the ACSS Aurora reticle is the icing on the cake that fully realizes the idea of an optic that increases first hit ratio whether at 800 meters or CQB distances. Let us tell you why:


    The Trijicon ACOG is a scope that requires no introduction. It is known for exceptional durability and optical clarity and has been a trusted optic for United States soldiers since 1993. 23 years later and this prism scope is still going strong in both the commercial and military markets with only one thing holding it back: the reticle. 23 years after the release of the ACOG and the reticle needed an update to accommodate for the changing dynamic of how soldiers use their rifles. With updated functionality like BDC calculated in 50-meter increments and holds for engaging fast moving targets, this reticle is a perfect match for the ACOG’s purpose-built use cases.


    While the Aurora may look like the original ACSS reticle, the windage holds and bullet drop compensation are calculated in meters instead of yards. The United States Military and police forces around the world train operators to range and engage targets using meters, so we designed a reticle that is familiar and intuitive for many of you. The BDC also utilizes 50-meter increments for even finer range estimation capabilities than ever before, all while still being extremely fast and easy to use. We’ve even built in the ability to range targets that are partially obscured. With only brief windows of presentation, knowing how far away the target is results in not only more effective fire but the ability to more accurately deploy additional assets as needed.

    Additionally, the new ranging bars located to the sides of the chevron tip reticle can be used as moving target leads. This feature is available on other ACSS reticles, but the difference that sets Aurora apart is the ability to lead targets moving up to 40mph – a feature that is increasingly important for soldiers – utilizing horizontal ranging bars that extend from each side of the chevron tip. The Aurora ACSS reticle is the first Primary Arms reticle designed specifically for military use, so combining it with the TA31 4×32 ACOG was the obvious choice.

    The ACOG’s durability and optical clarity are legendary, and they’ve been a trusted optic for our soldiers for decades. In 2016, Trijicon recognized the utility and capability of our Advanced Combined Sighting System (ACSS) reticle, making it the first 3rd party reticle commercially available in a factory Trijicon optic. We are very proud of that fact and set our team to work on something even better. Now for 2019, we have once again teamed up with Trijicon to bring the ACSS Aurora to the table. Designed from the ground up to wring every bit of performance out of these top-tier combat optics, the ACSS Aurora readily increases first hit probability and decreases time on target dramatically. For the latest and greatest combination of military grade optics and smart reticle design, look no further than TA31 4x ACOG combined with the Primary Arms ACSS Aurora reticle.


    While many reticles found in an ACOG include some capability to range targets and have some form of integrated BDC, none are equipped with the full set of features or the remarkable ease of use that come along with the ACSS Aurora. We’ve painstakingly developed and engineered this reticle and optic combat system to bring the toughest, most feature-rich performance to the people that demand it the most.


    Here at Primary Arms, we get pretty excited about bringing new products to you. This one is no different. You all told us exactly what you wanted, and we made it happen. You wanted a prism scope with a powerful ACSS reticle etched into the glass and modular mounting system. It had to have exceptional clarity, be made super tough, and it had to have absolutely no magnification. True 1X power for CQB supremacy.  It’s the Primary Arms 1X Compact Prism Scope with ACSS® Cyclops™ reticle, and we think it’s the most advanced CQB optic available today. Let us show you why your next close quarters rifle scope should be the Primary Arms 1X Cyclops.

    Red Dot Recap

    The “red dot” sight has always been the king of fast sight acquisition. For quick shooting up close where speed is the primary concern, a good red dot can get you on target faster than iron sights. Don’t get us wrong, we love red dots. We built our legacy on red dots. However, they aren’t perfect. There’s only so much you can do with a dot. We think a smarter, more advanced reticle system is just as important in CQB applications as it is when shooting out to longer ranges. Why settle for a just a dot?

    Shooting with the Primary Arms 1X ACSS Cyclops Prism Scope

    There are many shooters who find red dots problematic because they have astigmatism or other issues with how their eye perceives the reflected image of a red dot. A simple dot has enough limitations already, when your eyesight turns it into something undefined and incorrect, the issues with the red dot start to compound. Even if you have 20/20 vision, it’s still possible to run into performance problems with a red dot. So we wanted to build something different.

    The Smart 1x Alternative

    The Primary Arms 1X Compact Prism Scope with ACSS Cyclops reticle excels where the limitations of a red dot start to show. It features a permanently etched reticle like the rest of our line of prism scopes. This means that every shooter will see a crisp, defined reticle when they look through the glass. And a diopter ring on the ocular end ensures that the reticle will be perfectly in focus for your eyesight. The ACSS reticle design is more precise than what is possible with reflected LED emitter technology, and we’ll cover that more thoroughly below. Any optic’s purpose is to provide the highest amount of contrast possible in relation to the target, so we’ve powered the ACSS Cyclops through 11 brightness settings up to daylight bright. At a medium power, the cyclops will run continuously for 3,000 hours. But even if you do lose power, unlike a red dot the Cyclops’s etched reticle still shows up in black. Shooting in a washed out environment, the black reticle can be more useful than an illuminated one to pick up a high-contrast point of aim, giving you more utility in a larger number of situations.

    Looking Through The 1x Prism

    If you’ve run prism scopes on your rifles before, you’re probably used to keeping them pretty close to your eye. For a CQB optic that’s designed for fast target acquisition, we needed eye relief to be as long as we could make it. We stretched Cyclops’ eye relief out to nearly 4 inches, 3.7 to be exact. That’s a full inch more eye relief than our own 3x prism scopes, and 2 inches more than a 4X ACOG. So go ahead, extend that stock out a little, or make some room for your back up iron sights, the Cyclops won’t give you any issues.

    Unlike a red dot, Cyclops does have eye relief and exit pupil specifications. The exit pupil is pretty huge at 13mm, giving this scope a large and forgiving eye box. We built this for fast sight acquisition, so it needed nothing less. Once you have the diopter set to your eyes, you can easily shoot with both eyes open like a red dot, maintaining situational awareness and increasing your speed on target. When you add that capacity for speed to the ACSS Cyclops reticle, what you get is so much more than what a red dot can provide. Allow us to explain further…

    The Smartest Reticle System In The World

    The Horseshoe

    ACSS stands for Advanced Combined Sighting System, and it’s the smartest reticle system in the industry. To be as effective in CQB applications as red dots are, the reticle has to have a simple and intuitive point of aim. The Cyclops achieves this by utilizing the familiar CQB Horseshoe. For targets up close, where speed is everything, just place the horseshoe over the part of the target you want to hit and squeeze the trigger. To quickly hit targets out to 100 yards, just center the target inside the horseshoe and still achieve excellent first round hit probability. The outer edges of the horseshoe also function as moving target leads. For a target moving from right to left, you use the right edge of the horseshoe as your point of aim. The a target moving left to right, use the left edge of the horseshoe.

    ACSS Cyclops Reticle - Bullet Drop Compensation and Ranging Features Explained

    The Chevron and Bullet Drop Compensation

    If you need precision with the Cyclops, we’ve placed the patented ACSS Chevron in the center of the CQB horseshoe. The tip of the chevron provides an infinitely small aiming point that never obscures the target, so you can take a very precise shot when you need to. Sight in your rifle’s point of impact to the chevron tip at 50 yards to create a battle sight zero, meaning the round’s trajectory will impact an inch high at 100 yards before falling back down to the chevron tip at 200 yards. A second tip formed by the underside of the chevron forms a second point of aim, and the bottom of the chevron’s legs forms a third point of aim. How bullet drop compensation works out depends on the caliber. 5.56 NATO and other rounds with equivalent trajectories will reach 400 yards while the slower 7.62×39 and 300 BLK rounds will only make it 300 yards before crossing that point of aim.

    Auto Ranging

    Underneath the horseshoe and chevron are four horizontal ranging bars. These bars offer two methods to quickly estimate your range to a target. To vertically range the target, line up the bottom of the target with the bottom ranging bar and then measure upwards. If the top of the target reaches the highest ranging line, the target is 200 yards away. The other lines indicate 300 and 400-yard distances. The second ranging method is to use the horizontal the width of the ranging lines. Each line correlates to an 18-inch wide target at that specific distance, 200, 300, or 400 yards away. This is useful if you’re estimating the range of a target that’s partially obscured in long grass or behind a rise in the ground, making it impossible to range vertically. The ranging capabilities combined with the ACSS Chevron’s BDC calibration gives you the power to take more intelligent and accurate shots on targets at an unknown distance. For example, if you vertically range a target to approximately halfway between the 200-yard and 300-yard ranging lines, you can use that information to select a point of aim about halfway between the top and bottom chevron tips and give yourself the best possible opportunity to put that round on target.

    The Base Is Not Basic

    The Cyclops is compatible with any standard micro dot mount that you would use with a red dot sight. Because it’s a little larger than red dots, the center of the Cyclops will fall a little higher than a red dot’s would, so always be sure to zero properly. The included Picatinny rail base positions the center of the 1X Cyclops at 1.41 inches above the receiver, the same height as standard AR-15 iron sights. You can remove the base via four Torx screws located underneath. Later this year, Primary Arms will have two spacers available which can be placed between the included base and the scope body to raise the mounting height. PA1X-HM-SPCR-1.535  (PA1X-HM-SPCR-1.535-FDE for FDE version) will place the centerline of the Cyclops 1.54 inches above the receiver rail, or at lower 1/3rd co-witness height. The PA1X-HM-SPCR-1.64 (PA1X-HM-SPCR-1.64-FDE for FDE Version) riser will place the centerline of the optic 1.64” above the receiver rail as an extra tall option. A low mount will place the centerline just 1.05” above the receiver rail will be ideal for shooters using AK-47s and similar configurations.

    Mounting Options for the 1X Prism with ACSS Cyclops Reticle compared with the Advanced Micro Dot

    A Few More Things

    It is possible to use the Primary Arms 1X Cyclops in line, co-witnessing with iron sights like a typical red dot. When placed in line with iron sights, the front sight can be visible through the scope, so if you really want to, co-witness away. But the truth is, you don’t need to. Co-witnessing with a red dot is necessary in case your dot loses power. Even with no power, Cyclops still has a reticle there for you. If you’re insistent on co-witnessing, the iron sights should be zeroed while in line with the Cyclops to make sure your zero is true when you view it through the prism, which does inherently change the way your eye will perceive your iron sights.

    Magnifiers will also work with the 1X Cyclops when placed in the standard configuration behind the prism scope, but you will need to take a little extra time to get the magnifier focused on the reticle to get a crisp picture. When setting up a magnifier for the first time it is important to realize that you are now employing two separate optical systems, and each needs to be calibrated to your eye. We recommend to first adjust the diopter ring on the magnifier to the furthest out position. With the magnifier diopter ring in the furthest out position and in line with the 1X Cyclops, adjust the Cyclops’ diopter ring until the reticle is crisp and clear. Flip the magnifier to the side and check the reticle image unmagnified. If the reticle image is not clear unmagnified, continue to make small adjustments to the Cyclops’ diopter ring with the magnifier in line and out of line until the difference between the two is eliminated or minimalized to fit your needs. For some individuals, this difference may never be eliminated completely, and the Cyclops’ diopter will need a slight adjustment each time the magnifier is moved in line or out of line behind the prism scope. This should be expected, as it is inherent to the unique combination of the two optical systems.

    In addition to the configuration described above, a typical magnifier can be placed in front of the PA 1X prism scope. However, it will introduce a large amount of point-of-aim shift, parallax and overall unreliability of the optical system. We don’t recommend using a magnifier with the 1X Cyclops in this configuration.

    Shooting the Primary Arms 1x Prism with ACSS Cyclops Reticle

    So Good We Guarantee It – For Life

    Lots of company’s warranties cover “manufacture defects” or flaws in workmanship or materials. If there are manufacturer defects present in an optic, it was there when that optic left the warehouse. 15,000 rounds put downrange are not going to magically make a manufacturer defect appear. It was either there, or it wasn’t. At Primary Arms, we believe in what we build. We don’t bring a new product to market until it’s stood up to our exceptionally rigorous testing process, and it doesn’t leave our facility in Houston, Texas to arrive at your door until it’s been inspected by hand. If it can take the abuse we put it through, pass our inspection, and still perform to our exacting standards, only then are we confident that it will absolutely blow away your expectations. We make optics to last a lifetime. Because we’re so confident in that, we stand behind our products for a lifetime. It’s our promise to you. If your Cyclops ever becomes damaged to the point of failure we will repair it for you or send you a new one. No questions asked. So go ahead. Buy with confidence.

    You asked for it, and now it is here. They’re bound to go fast, but they’re here to stay, so get your hands on one as soon as you can and check back often if they’re out of stock. The PA 1X Cyclops is the smartest, most capable CQB optic we’ve ever seen, and we think you’ll agree.

In this reticle. The outer CBQ horseshoe is removed. A smaller horseshoe which draws the eye to the target is placed around the center dot. The vertical ranging bracket is present to the right of the main BDC and horizontal ranging ladder, and wind holds and moving target leads fall similarly alongside the bullet drop compensation. The 5X Gen II provides the same field of view as the 3X at 100 yards, weighs in at 18.4 ounces, only 2.4 ounces more than the 3X, and is windage and elevation adjustable at 1/3 MOA. The 5X’s ACSS reticle also features both red and green illumination.

    We are excited to announce this new generation of Primary Arms prism scopes. All these improvements have allowed us to take what were high-quality, durable, and versatile prism scopes and make them even better. Prism scopes are some of the most popular optics solutions for AR-15 and AR-308 style rifles, so look no further than the new Gen II 3X and 5X scopes from Primary Arms for your next prism scope.

    • Lifetime Warranty
    • Improved Waterproofing and Toughness
    • 50,000 Hour Battery Life

    HOUSTON, TEXAS – Primary Arms Optics introduces an all-new micro red dot sight, the MD-RB-AD, featuring a lifetime warranty and estimated 50,000 hours of battery life.

    The Microdot, Removable Base, Advanced sight (MD-RB-AD) takes everything learned from our previous red dot sights and refines it a step further. MD-RB-AD features an estimated 50,000 hours of battery life from the included CR2032 battery, powering an ultra-sharp 2 MOA dot. Fully multicoated lenses and an ultra low profile emitter ensure a clean sight picture with minimal lens tint. Eleven brightness settings are controlled by the rotary knob on the right side. The first two settings are compatible with night vision units and cannot be seen by the naked eye. The brightest settings are daylight bright. The illumination knob physically stops at “0” with the red dot turned off.

    Covered by the Primary Arms lifetime warranty, MD-RB-AD is designed for use on heavy recoiling firearms such as shotguns. Constructed of 6061 aluminum throughout, MD-RB-AD features a Type II anodized matte black finish. Waterproofing is improved over previous models—for example, the turret caps are now aluminum instead of plastic and tighten down around the waterproofing O-rings until metal-to-metal contact with the scope body. When removed, the turret caps can be used to adjust windage and elevation.

    MD-RB-AD comes with a removable MIL-STD-1913 Picatinny base. With the base removed, the scope body is compatible with industry standard micro mount systems, enabling MD-RB-AD to be mounted correctly on a wide variety of firearms.

    Available in matte black or flat dark earth, MD-RB-AD is priced at $ 149.99.

    • Lifetime Warranty
    • Locking, Resettable Turrets and Replaceable Power Ring Fin
    • Patented ACSS® R-Grid 2B™ Mil Reticle

    HOUSTON, TEXAS – The Primary Arms 3-18X50 First Focal Plane scope is changing shooters’ expectations about what a precision rifle scope in this class can do. It features the improved, optimized ACSS R-Grid 2B reticle, an unbeatable combination of quickness at low magnification and precision at high magnification.

    This all-new scope enables the precision rifle shooter to acquire a sight picture very quickly for snap shooting situations at short range and low magnification. Yet a full 18x magnification on the high end is possible for the first time in an optic of this class, enabling high precision shots exceeding 1,000 yards. Innovations like a removable, replaceable power ring fin have combined with features demanded by our customers, like locking, zero-resettable target turrets.

    The R-Grid 2B reticle is a refinement worth waiting for. The familiar ACSS chevron and horseshoe remain for up close snap shooting. Auto-ranging will be familiar to ACSS users. The original line grid has been replaced with a dot matrix grid, giving more precise holdover references with less clutter, and extended down to 15 Mil below center.
