***All gas gun customers should be aware that repeated cycling of an unfired cartridge can cause the projectile’s crimp to fail and the bullet to become loose. This is more prevalent with large monolithic projectiles because the copper’s surface is less yeilding. Due to the AR10 platform’s lack of uniformity or military specifications we are unable to predict whether your firearm is more or less likely to cause this characteristic. Our standard recommendation to prevent this occurrence is to polish your firearm’s feed ramp and check the headspace of your weapon***
