Military-style semi-auto rifles often lack firing pin retraction springs. Without careful ammunition assembly a "slam-fire" can happen before the bolt locks. The military uses different techniques and components to manage this including primers with different sensitivity specifications than their commercial equivalents. These CCI 41 small primersfor 5.56mm reduce the risk of a slam-fire when other elements become unpredictable*. When reloading for a military semi-auto consider CCI Military primers
Effective slam-fire prevention involves more than specialized primers. Factors like headspace chamber condition firing pin shape and protrusion bolt velocity cartridge case condition and more can influence slam-fire potential.
