Global Ordnance 5.56 NATO M193 55-grain FMJ ammunition delivers military-spec performance for AR-15s, carbines, and other modern rifle platforms. Built to NATO STANAG 4172 and MIL-C-9963F standards, this factory-new brass-cased, Boxer-primed round is engineered for reliable function across a wide range of shooting applications—from high-volume range days to tactical training and competition prep. The reloadable brass cases make it practical for shooters who reload or want to preserve brass for future use.
Whether you're running drills on the range, zeroing a new rifle, or stocking up for regular practice, this ammunition performs consistently across temperature extremes and delivers tight shot groups. At 55 grains, the M193 bullet weight is the original specification for 5.56 NATO and remains a favorite among shooters who value proven design and predictable ballistics. Global Ordnance engineered this round to handle the demands of semi-auto platforms without the fluff—just solid, tested ammunition that goes where you point it.
Sold in convenient 20-round boxes, this is practical ammunition for serious shooters. The FMJ construction ensures reliable chambering and function in any 5.56-compatible rifle, and the factory testing for velocity, pressure, and accuracy means you know what to expect downrange. If you shoot frequently and demand consistency without compromise, Global Ordnance M193 is ammunition built for the work.
