LARGE RIFLE MILITARY PRIMERS FOR 7.62MM AMMO Reviews & Ratings

Military-style semi-auto rifles seldom have firing pin retraction springs. If care is not used in assembling ammunition, a “slam-fire” can occur before the bolt locks. The military arsenals accomplish this using different techniques and components—including different primer sensitivity specifications—from their commercial counterparts. CCI makes rifle primers for commercial sale that matches military sensitivity specs that reduce the chance of a slam-fire when other factors go out of control. If you’re reloading for a military semi-auto, look to CCI Military primers.

Effective slam-fire prevention requires more than special primers. Headspace, chamber condition, firing pin shape and protrusion, bolt velocity, cartridge case condition, and other factors can affect slam-fire potential.

Milspec Primers

Product is great. Shipper wanted to scan my drivers license. I show to verify age. Did not allow any scan.

Great for 6.5mm Grendel

I have two 6.5mm Grendels that I use these primers for. They handle the pressure and ball powders very well in all temperatures.

# 1 choice for Military Type Weapons

They are made by CCI, can't get to much better than that! Now if I can just get the 34's for my M1A, all would be well.

CCI 41 primers

Use because of thicker primer cup, much safer using in AR platform.

The Best Primers For AR Rifles

CCI #41 primers are the best primers for any ammo reloaded for shooting in AR-15 type rifles. I use these in 5.56mm NATO, 6.5 Grendel & 6mm ARC reloads. Never had a slam-fire with them but at the same time never had a fail to fire. Accuracy with those 3 rifles has been superb!

Brownells can be trusted

This review is more for Brownells than the #41s, whose specs speak for themselves. Been searching for #41s for over 8 months with no luck and there are numerous scams out there who claim to have them but don't. Friend at gun club suggested Brownells and I tried them very cautiously and was successful in getting the primers as advertised. I now TRUST Brownells, which for me is a difficult thing to earn. Been using other SRP for 5.56 reloads and so far had one slam fire. Do not expect anymore using the #41s. Brownells ... thank you for being honest and doing what you say. This is in short supply these days.

Primers at last!

These are the first large rifle primers I've been able to buy for awhile. I'm now down to my last 200 CCI200 LR primers and these 34's will have to substitute. I plan on dropping the amount of powder I use down some and work up a new load using these hotter primers.

Thank You!!!

In this Covid world what can anyone say but Thank You Brownells for having merchandise in stock AND notifying me as I requested!!!!!
