CCI 41 Small Rifle 5.56mm NATO-Spec Military Primers
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. CCI #41 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.
CCI 41 Small Rifle 5.56mm Military Primers specifications:
- Mil-spec sensitivity
- Initiator mix optimized for ball/spherical propellants
- Small (No. 41) rifle
- Use the same data as CCI Magnum primers
- Military-style semi-automatic rifles
Ensure safer reloading with CCI #41 primers designed to reduce slam-fire risks in military-style rifles.
Roy From Placentia Ca. –
I use the CCI No. 41 primers for .223 Rem/5.56 NATO, 300 Blackout, 6.5 Grendel and 450 Bushmaster. I don’t experience any primer punch through/back out, fail to fire or primer slam fire (all AR uppers that I own use Titanium Firing Pins). I’ve never lost confidence in using these primers for my AR15 platforms or my Mini 14’s. I’ve been through about 5,000+ CCI No. 41’s with another 3,000 of the above case assortment on deck and in the pipeline right now (Case Polisher running day and night as I type this review) Based on my experience only, I highly recommend that you give this CCI product a try.

I use these primers to reload 5.56 rifle loads. All of them that I have used have operated flawlessly. They come in the industry standard 100/box which make them easy to store and easy to inventory. I have absolutely no negatives to report about this product.

I use CCI #41 for 300 Blackout, 6.5 Grendel, and 5.56 reloads in my AR15 style firearms. Ignites the powders efficiently, for good burns in both short barrels and standard 16,18-, and 20-inch barrels.
