GS-022 FMJ 55 Gr 5.56 NATO Ammunition

Fiocchi’s 5.56 M193 is a dependable 55‑grain FMJ‑BT round built for shooters who run their rifles regularly and expect consistent performance every time they load a mag. It’s loaded to true 5.56 NATO pressures, pushing a 3240 FPS muzzle velocity for the fast, predictable behavior AR‑15 shooters rely on. Each cartridge uses a brass case, non‑corrosive primer, and clean‑burning powder that keeps your rifle running smoother through long training sessions. The M193 profile delivers the classic 55‑grain feel — stable, accurate enough for drills, and ideal for high‑volume range work. If you want straightforward, no‑nonsense 5.56 that runs clean and stays consistent, this is it. 50 rounds per box.
