This 5.56x45mm  ammunition was manufactured by Winchester for a contract. Designed as a barrier defeating round with superior penetration and superb ballistic stability in the AR-15 rifle. The load features the 62 grain green tip Penetrator bullet, which utilizes a steel tip at the front of the lead core and a thick copper base.

The reloadable brass case is boxer primed and loaded with non-corrosive powder and primer. Our buyers were able to obtain a limited supply of this high-performance ammunition for our customers. Some cases may have slight dings or imperfections.

Please Note: While the 5.56x45mm  will fit in a .223 Remington chamber, the 5.56 is a military round that runs at higher pressures than its .223 counterpart and is not recommended to be fired in a .223 Remington Chamber.
