Constructed from QPQ Treated 17-4 and ordnance grade steel, Griffin M2 Sights were designed to be the correct product for every backup sight application. A shooter can use these durable, low profile sights in a 12 o'clock mounted application while having the flexibility to reconfigure them to ambidextrous 45 degree angle sights using the alternate and available angle plates. The full M2 deployment kit includes the front and rear sight assemblies as well as both vertical and angled bases for a complete modular system. The front A2 sight provides elevation adjustment while ensuring maximum aftermarket support for your favorite post, be it tritium, fiber optic, match grade, or otherwise. An extremely low profile, snag resistant, slotted rear windage screw, affords easy but more importantly secure adjustability. Robust spring tension of both front and rear flip up assemblies ensures accurate repeatability every time the sight towers are actuated.
