CCI 41 Primers 5.56 Military Small Rifle
Military-style semi-automatic rifles rarely have springs that retract the firing pin.
If ammunition is not properly assembled, “explosion” may occur before the pin engages.
Military arsenals use different technologies and components to achieve this, including primer sensitivity specifications that differ from commercial ones.
CCI manufactures rifle primers for commercial sale that meet military sensitivity specifications, reducing the likelihood of a slam-fire when other factors are out of control.
If you’re reloading for a military semi-auto, look to CCI Military primers.
Effective slam-fire prevention necessitates more than just special primers.
Headspace, chamber condition, firing pin shape and protrusion, bolt velocity, cartridge case condition, and other factors can all influence slam-fire potential.

Not the hottest primer on the market, just mil spec safe. If you are using a light bcg these are a must. I’ve never had a slam fire and don’t want one.
