Primary Arms MicroPrism™ Straight Riser - 1.93″.

The Primary Arms MicroPrism 1.93” Straight Riser is an optional accessory for your favorite Primary Arms SLx® MicroPrism Optic System. When used with the factory MicroPrism mounts, this riser will bring the centerline height of your MicroPrism to 1.93 inches, which allows for a more ‘heads up’ shooting position. Many believe this height to be faster and more comfortable than traditional optic heights, especially when used in conjunction with night vision devices or respiration/CBRN gear. This riser features the same reliable materials and construction as your factory risers and mounting equipment, and it comes backed with a lifetime warranty.
