TruGlo has seriously stepped up the game with the Tru-Tec series of red dot sights made with the durability and feature set of optics found at twice the price, according to the company. The Tru-Tec Xtreme features a motion-sensing auto on / off, digital controls, years of battery life, and an included cantilever mount designed for absolute co-witness on AR-15/M4 carbine platforms.
Completely self-contained, the DryFireMag fits into the magazine well with no alterations to your pistol. Installs in seconds. Simulates trigger release and reset without using the firing pin.
