Tried out my new CMMG .22lr kit.

[41 Colt]

Shot Winchester Dyna Points. I only had one feeding issue, after firing the very first round with the stock CMMG mag the next round wound up pointing straight up and got jammed between the bolt carrier and conversion insert.

After that it went nearly perfect with my six other BDM mags except for a dud round.

I have an ACOG mounted on my 14.5" upper and to hit my gong at 80yrds I had to center the 600m mark of the reticle on the gong.

I had fun.

Im thinking about getting the kit too. What twist is your barrel? Did you try to get any decent groupings?

 

[Onagoth]

Sweet, I've always wondered what these conversion kits cost and how many rounds the mag holds.

 

[41 Colt]

I didn't put any rounds on paper so I can't comment on groupings.

I am using a 1/7 twist barrel.

Onagoth, the kit was about $330 with one mag from Questar. The mags hold I think 26 rounds.

 

[polskadude]

$334.99

27 rounds per mag I believe

or 26...

Cool, I have a CMMG M4, with 1/7 twist, I heard they like 1/12+ twists, but i hear alot of ppl using 1/7.

I got mine a few months ago it is very reliable, I have only shot AE 40gr high velocity with it and its very reliable, all you need is someone else to load the mags

Onagoth if you want to look at mine and can bring it tomorrow for you to check out....

 

[Markus88]

what gun is this a conversion of? the ruger 10/22? or?

 

[41 Colt]

It is for the AR15, replaces the BCG and is based on the Atchisson/Ciener design.

Mine runs like a sewing machine. Great bit of kit.

 

[iamcanadianeh]

Mine runs pretty good for the most part. I've noticed that I have to keep it really really clean and lubed though, otherwise I get jams. Anyone have jams where the round gets stuck between the very front part of the charging handle and the conversion bolt? Maybe its cause my AR is 12.5?


12.5 inches that is

 

[NaOH]

I had a failure on my first round. A couple thousand rounds later and not one problem. I clean the 22 conversion every 4-500 rounds.

14.5" barrel.

What are you using for ammo?

 

[NaOH]

Federal bulk packs from Wally World or Canadian Tire.

I've run 4 different types of ammo with the same results. I clean it every 4-500 rounds and oil it every time I shoot it.
