Primary Arms 1X Compact Prism Scope - Illuminated ACSS Cyclops Reticle


The Primary Arms 1X Compact 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 dot. Unlike most prism optics, the 1X Compact Prism Scope has a generous 3.7 inches of eye relief combined with a massive 13mm exit pupil to provide an exceptionally 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.
