Mil-Spec No.41 / 5.56 Primer | Small Rifle

CCI #41 Small Rifle Primers are specifically engineered to meet U.S. Military specifications for 5.56mm NATO applications, making them an ideal choice for reloaders working with military-style semi-automatic rifles. These primers are designed to reduce the risk of slam-fires, a crucial safety feature for rifles with floating firing pins. Each primer offers consistent ignition and reliable performance even under demanding conditions.

Like all primers in the CCI line, the #41 Small Rifle primers are continuously tested and refined to ensure optimal sensitivity and seating. They are easy to install and highly compatible with progressive and automated reloading systems, making them a top pick for high-volume reloaders and those seeking military-grade dependability.

These primers feature a specialized cup thickness and hardness that help resist slam-firing in AR-platform rifles, all while maintaining the same performance data as standard CCI magnum primers. This allows for consistent ballistics without the need to adjust your existing load data, offering convenience along with enhanced safety.

The modern non-corrosive and non-mercuric initiator mix ensures a cleaner burn, which contributes to reduced fouling in your firearm and extends maintenance intervals. Whether you’re prepping rounds for tactical training, competitive shooting, or defense, CCI #41 primers deliver uniform ignition and reliable cycling shot after shot.

Trusted by reloaders who demand military-spec performance in their handloads, CCI #41 Small Rifle Primers are packaged in either retail or commercial configurations and are a must-have for those building dependable 5.56mm or .223 Remington ammunition. Designed with precision and purpose, they represent CCI’s long-standing commitment to safety, consistency, and quality.

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.
