This is military style ammunition for your military style AR-15. This ammunition is for use only for chambers marked 5.56 NATO, as are most AR-15 carbines and rifles. Do not use it in sporting rifle chambers marked .223.

Many rifles chambered in 5.56 NATO are not realizing their full potential when shooting 223 Rem ammo. To get all the performance 5.56 NATO can deliver, you need a 5.56 NATO load. 5.56 NATO chambered rifles were designed to take advantage of the higher pressure of the 5.56 NATO cartridge'shigher pressure translates to increased velocity, higher energy and harder-hitting performance. CAUTION: Firing 5.56 NATO ammunition in 223 Remington chambers will produce a dramatic rise in pressure which increases stress on the weapon, risking wear, permanent damage and/or injury.

"XM193 product is first run, first quality product manufactured by the Lake City Ammunition plant in Independence, Missouri for Federal Cartridge. It is made to Federal specifications typical for commercial ammunition. All XM193 product is the same regardless of the sku or part number. (ie. XM193C is the same as XM193F, XM193CBP and etc…) The only difference is the package configuration." This same round is also packaged as XM193 in a brown box.

Jason Nash, Group Lead, Communications - ATK Ammunition and Related Products Group: "We've had several questions regarding the XM designation and following is our official statement regarding what the product is. XM193 ammunition is 5.56mm contract overrun material. It may not meet all of the mil-spec requirements, however, it does meet all requirements of commercial ammunition for pressure, form, fit and function. Like any other mass-produced product, there are often imperfections in either appearance or non-functional mechanics. As we all know, the military is very stringent in their requirements and for good reason. This being the case, it doesn't take much to fall outside of those parameters."
