CCI Small Rifle 5.56mm NATO-Spec Military Primers #41 Box of 1000 (10 Trays of 100) CCI Primers are continuously tested and improved. As a result today’s CCI primers are more sensitive, easier to seat and more compatible with progressive and automated loading equipment than ever before. CCI Small Rifle 5.56mm NATO-Spec Military Primers #41 Box of 1000 (10 Trays of 100) They utilize modern non-corrosive and non-mercuric initiator mixes for the cleanest burn possible.

Number 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.

    First time I use cci 41 work fine no misfires (100 rd.)

  4. John Intoppa

    Yes I bought 2 to start with. One to go on reloading bench.
    Thay are good primers. When that’s all Midway USA Has in stock for the last year and a half. I prefer bench rest primers

  5. Therese Dimuzio

    I have had good results …
    I have had good results with these primers in my .223 hand loads for my Bushmaster but found them hard to seat in regular Winchester or Remington brass at times.

    I have purchased this product, many times
    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.

    FAST shipping!
    I grabbed a brick of these when they became available. I switched to 41’s after finding out that CCI 400’s can’t handle modern-pressure (50,000+ psi) loads in 223 or 308 Win/260 Rem/6.5 CM) with small rifle primer cases – lots of pierced primers. In my 223 loads with my previous brick of CCI 41s (behind 23.7 gn AA2460 and 69 gn SMKs in GD “A”-stamped brass) I’m getting 10-round SDs in the low to mid teens, and 2-1/2″ 10-round groups at 300 yards through a Stag lefty upper with a WOA 20″ 1:8″ HBAR. I ordered these on Tuesday morning and they arrived here (UPS Hazmat ground freight) in the middle of the Western desert 76 hours later, and Christmas is only a week away. Good work, Midfirarms and UPS!

    Great for at style rifles
    Reloading for ar price has gotten stupid was 159 for 5ths now for 1ths

    Solved my perforated primer issue for my 357 mag revolver
    I have an 1873 revolver in 357 mag. I dearly love this firearm, but it has a very strong hammer spring and about 50% of the time the firing pin perforates the standard primer leaving the indentation black colored. I make my own ammo, and decided to try these No 41’s as they are made of tougher material per nato spec. Problem solved.. have had 100% reliability and no more primer perforations. Don’t know how they would work for other people as often these primers don’t work well for handguns. For me, they do the job.
