Winchester M193 5.56×45mm NATO — 55 gr FMJ — 200/Box
Reliable range-grade 5.56 NATO in a bulk training pack.
This 200-round box of Winchester M193 5.56×45mm NATO ammunition delivers consistent, target-grade performance for training, practice, and high-volume range sessions. The 55-grain full metal jacket projectile feeds and cycles reliably in AR-style rifles and other 5.56 NATO-spec platforms while providing predictable trajectories for sighting, drills, and marksmanship practice.
