Lake City Rifle Ammunition in 5.56mm M193 is a reliable, full-power round built to the original military specification. This case lot contains 600 rounds packaged in four 150-round boxes, making it ideal for serious rifle shooters, competitive shooters, or anyone running high-round-count training sessions. The 55-grain full metal jacket (FMJ) projectile delivers consistent ballistics and reliable feeding in AR-15s and other 5.56mm rifles, with the predictable performance that comes from Lake City's long track record as a U.S. military ammunition producer.

Whether you're working on marksmanship fundamentals, running a carbine course, or stocking up for regular range time, M193 remains one of the most widely used 5.56mm loads across civilian and professional shooting communities. The FMJ construction is straightforward and proven—no tricks, no premium pricing, just honest ammunition that cycles reliably and shoots to zero.

The case format works well for shooters who want to buy in volume without managing dozens of small boxes. Four 150-round boxes break down easily for transport or storage, and the quantity supports extended range sessions or multiple shooters without constant restocking.
