The high-end Razor red dot is an open-top reflex sight built for top-tier performance and incredible versatility. The large, clear and crisp window provides edge-to-edge sharpness with a wide field of view and is protected by a thick and durable aluminum housing. Dot size is available in 3 MOA or 6 MOA for your choice between a more precise aiming point on a rifle or one that’s extremely quick to acquire on a handgun. Side-load battery tray makes for quick battery changes without removing the sight from your firearm. A great fit for rifles and shotguns. Rugged and durable, the Razor comes in at 1.3 ounces (2.4 ounces with its included, low Picatinny mount).
