The Mil-Spec No. 34/7.62 primer provides the most reliable, consistent ignition. It's built to military specifications and specifically designed for use in 7.62 cartridges. Number 34 Mil-spec primers are made to the same specifications of the U.S. Military and reduce the chances of a slam-fire. While designed for you in Military-style semi-auto rifles, they use the same data as CCI magnum primers.

Note from CCI: Effective slam-fire prevention requires more than mil-spec primers. Headspace, chamber condition, firing pin shape and protrusion, bolt velocity, case condition and other factors can affect slam-fire potential.
