Win Usa Lake City M193 Rifle Ammunition 5.56Mm 55 Gr. Fmj 3240 Fps 100/Ct

Winchester USA Lake City M193 5.56mm rifle ammunition delivers dependable, mil-spec performance in a practical 100-round package. Built to the same standards trusted by military and law enforcement, this 55-grain full metal jacket load runs at 3,240 fps, making it a solid choice for range training, target practice, and general shooting. Whether you're zeroing a new rifle, running drills, or stocking reliable centerfire ammo, Lake City brass offers the consistency you expect from Winchester at a working shooter's price point.

The 55-grain FMJ bullet is the classic 5.56 load—accurate enough for precision work, tough enough for high-volume sessions. Brass-cased and boxer-primed, it's also reloadable, so handloaders can reload spent cases and keep their cost-per-round down over time. The 100-round count fits naturally into a range bag or ammo can without taking up excessive space, and the sturdy packaging protects rounds in transit.

Lake City ammunition carries generations of mil-spec credibility: it was the standard U.S. military 5.56 load, and Winchester's commitment to those exacting standards remains unchanged. If you're running AR-15s, M4-pattern rifles, or any 5.56 NATO chamber, this round will perform reliably shot after shot, outing-of-the-box or after a reload cycle.

Frequently Asked Questions

Yes. The 5.56mm NATO cartridge is standard for AR-15 rifles and any firearm chambered in 5.56. Always verify your rifle's chamber marking before loading.

Can I reload these cases?

Yes. The brass cases are boxer-primed, which means they use a centrally-located single primer pocket—the standard reloading setup. After firing, you can deprime, resize, reprime, and reload them.

Is this military ammo or civilian ammunition?

This is civilian Winchester ammunition manufactured to military specifications. It is not surplus mil-spec ammo, but new production built to the same standards.
