Griffin Armament M2 Flip-Up Sight Set for AR-15 - Stainless Steel Matte Finish

The Griffin Armament M2 flip-up sight set for AR-15 gives you true backup iron sights without the compromise. Built from QPQ-treated 17-4 stainless steel and ordnance-grade steel, these low-profile sights weigh just 2.5 ounces and mount directly to any Picatinny rail system. What sets the M2 apart is its patent-pending modular base plate system—a feature you won't find on budget backup sights. You get both a vertical 12 o'clock configuration and the flexibility to swap in angled plates for 45-degree offset mounting, all from the same sight assembly. No locked-in compromises; one system, multiple applications.

The front sight includes an A2-profile post that accepts popular aftermarket options—tritium, fiber optic, match-grade, or standard GI posts—so you're not stuck with what ships in the box. Elevation adjustment happens at the front, while a slotted rear windage screw keeps things secure and easy to dial. Both flip-up mechanisms feature robust spring tension, ensuring consistent, repeatable deployment every time you need them. The complete set includes front and rear sight assemblies plus vertical and angled base plates, giving you a genuinely modular system ready for whatever configuration your rifle demands.

Whether you're running a dedicated optic with backup irons or testing a new rifle setup, the M2s work in the rain, fog, snow, and dust—no batteries, no glass to break. They're snag-resistant, compact, and built to stay put. If you're the type to evolve your rifle rather than lock into a single setup, these sights grow with you.
