Brand name Factory Brass cased ammo. We currently do not endorse any one particular type as not all ammunition produces the same results. We recommend visiting the range with a variety of ammunition and finding what best suits your rifle. Ammunition selection is very important. Not all ammunition is designed for use in an auto-loading firearm. We like to see ammunition used in our rifles that is made specifically for auto loaders; this is especially important in 7.62mm rifles. The brass should be manufactured to military standards with hard brass, staked primers, and tight neck seals or crimped necks. The projectile should be an FMJ, OTM, or plastic tipped design to allow for a smooth transition from the magazine to the chamber. If you experience dropped primers, discontinue the use of that ammunition. Dropped primers may become lodged in the weapon, resulting in a serious stoppage. Soft brass can result in the flow of brass into the ejector hole of the bolt face. When the bolt rotates out of battery, the bolt shears off the brass that flowed and can create unwanted debris in the firearm. The tip of soft-tipped ammunition can become deformed during the feed cycle, resulting in a stoppage. Blunt tipped projectiles may create stoppages by impacting the receiver or magazine during the feeding process.
