Primary Arms Rifle Scopes
Prism Scope Frequently Asked Questions
Prism Scopes offer a fixed magnification in a relatively small package by redirecting light through an internal glass prism. You may read terms like Pechan prism, Porro prism or Roof prism when researching these scopes, but the bottom line is that this technology is highly durable and extremely well proven.
Prism scopes, like the Primary Arms MicroPrism™ are a superb choice for a basic and super tough do everything scope. Simple to install and operate, prism scopes are lighter than conventional rifle scopes with similar magnification levels and features. Despite their compact form-factor, prism scopes are exceedingly rugged.
With decades of battlefield exposure, prism optics like the Trijicon ACOG series have proven their reliability in the most hazardous conditions on earth. No optic is without compromise. Prism scopes are only a fixed magnification, so they lack the versatility of variable zoom optics.
