Hell Yeah!!!


Ever notice that you can hit the range, do a few drills and clear your head?

I just put 75 rounds (Federal 40gr) thru my BPM CQB AR15.
Instead of it costing me $75+… I only spent @ $7.50!

My CMMG .22LR AR Conversion Kit arrived today. Was ordering some parts the other day, saw this item , read a few reviews and thought I’d give it a go.

10 second install, pull out BCG, drop in CMMG Conversion Kit BCG.
Load up mags and BOOM! I’m on the range and pinging steel. Sights were still dead on @ 50m. No malfunctions.

Great item! I’d recommend it to anyone!
$1.00 a round VS. 0.10 (a dime!) a round.
Cost under $200.
Hitting the range, doing LIVE DRILLS. and still using my everyday platform… PRICELESS!!!

Great fun!!!!


I took a chance after reading reviews. Then watched U tube. I figured the worst thing that could happen is I would need to send it back. NO WAY!!
I oiled it up, installed it and havent looked back... Works great. About 800 round threw it now. A friend went shooting with me and he also injoyed it now him and 2 of his friends have them. One thing you must do!!! BUY the loader it will be easer on your thumbs. Crossdrawjohn.

I purchased the CMMG .22 LR Conversion Kit- Bravo with 3 magazines a few months ago and just got to try it out. I was absolutely pleased with it’s performance. I ran CCI Mini Mags, Winchester Wildcats and Remington Thunderbolts through it for a total of about 300 rounds and it performed flawlessly with all. Gotta say I had a blast with cheap ammo and am very happy with my purchase.

I finally took the plunge on this conversation kit due to the price of ammo. Can't shoot steel case indoors, and I can't afford a dollar per trigger pull to practice. Enter the CMMG Bravo. It worked perfectly my first trip to the range. Added a little gin oil to get it clacking smoothly. Fires as quickly as you can pull the trigger, perfectly accurate with my 10.5 5.56mm barrel. Zero recoil. My hands, eyes, body do everything they are supposed to to run my AR. Glad I bought it.

Too much fun!

I ordered this the Thursday before Easter. Showed up the following Monday as scheduled.
I unpacked it, put a little oil on it and put it in my Ruger 556. Went outside and ran 300 rounds through it without any failure to feed or fire problems. Very impressed.
Bought a box of Federal 22LR for 6 cents a round, compared to 223 for 40 cents, that makes this conversion kit a no brainer.

Outstanding performance from this CMMG kit!

Grabbed this CMMG conversion kit during a flash sale, this past weekend. Ordered on a Sunday and it arrived the following Wednesday. Thanks, Primary Arms, for a fantastic deal and the speedy delivery!

Well, it arrived yesterday. As such, I took it out to my club this morning. Vetted this CMMG conversion kit on a 10.5" AR-15, first. It ran some 350 rounds of CCI Mini Mags flawlessly. I did expect some hiccups. However, the unit ran extremely well and without any issues. This kit will afford me the ability to practice with my other ARs at a significantly reduced costs.

While the CMMG magazines ran flawlessly, they were a pain to load. The process is quite slow. Initially, I could only load each mag with 20 rounds. Fortunately, I brought along my old M&P 15-22 25 round mags. They ran perfectly and were a breeze to load.

So, if you have been on the fence about getting this CMMG conversion kit . . . Just get it!

Unfortunately POA from 22 to 233 changes significantly, even at short distances


I like shooting 22 and was hoping that some 223 zero would work with 22 without having to change my optics zero.
I have more to learn but here is what I have discovered so far:

A 60 yard zero with 223:
Can be obtained by zero'ing 22 rounds, at 96 feet (32 yards) and have it be 3.5" low from what you are aiming at. That so far has given me a rough 60 yard CQB zero for 223.

This is much less useful if you think that you can zero with 223 - throw in the 22 bolt and be in business and actually hit things.

If would be very interesting to use a ballistic calculator and look at various 223 and 22 zeros and see if you could somehow have a 223 zero useful with 22.


Best Bang for the Buck!
