Primary Arms Cyclops ACSS

The Primary Arms Cyclops Prism Scope with ACSS Cyclops reticle combines the durability and flexibility of an etched reticle with the speed and ease of use of a red/green dot. Unlike most prism optics, the 1X Compact Prism Scope has a generous 3.7 inches of eye relief combined with a massive 13 mm exit pupil to provide a very forgiving eye box. This allows for a high degree of efficiency in red dot style shooting. Keeping both eyes open for fast target acquisition in a variety of positions and circumstances that no other prism scope can touch. The 1X Compact Prism Scope’s included 1913 MIL STD Picatinny rail mount is removable, and the scope body is compatible with industry standard microdot mounts.

 A heavy horseshoe makes rapid acquisition and reflex sight style snap shooting a breeze, especially when used in conjunction with the red or green reticle illumination. When speed is less important, the center chevron tip offers an infinitely precise point of aim that won’t cover the target, allowing for remarkable accuracy at long distances. The etched ACSS reticle combined with the fast focus eyepiece make this optic an excellent option for shooters with astigmatism.  A clear sight picture will lead to more confident hits and better accuracy at further distances than ever before.

The 1X Prism Scope body is just as tough as the rest of our proven line of prism rifle scopes. During durability testing, the 1X Prism Scope outlived not one, but TWO piston driven .308 Winchester rifles, selected specifically for their reputation for driving optics to failure. Each optic is finished with a tough Type III hardcoat anodized black, under an equally tough FDE Ceramic finish to keep your scope looking great for years.
