CMMG 22LR AR conversion with one 25 round magazine reduced to 150 or offer

dmatzinger · Oct 19, 2021

This is the closest thing i can find to the one i bought, only difference is the one i have comes with 1 25 round magazine. I have decided to build dedicated 22 lr upper, and the collar to make this work is out of stock, but i can by the "assembly" with the barrel, bolt and collar. If i can sell this before the collar is back instock, i will, and if not i will wait. I would like to get 180 for it, it has only been shot 50 rounds.
thanks

These are a blast. They work well for indoor ranges where centerfire ammo is not permitted and outdoor plinking. Pretty damn accurate at shorter ranges. I with a bag and this installed I can make a ragged hole at 25 yards out of a .223/5.56 1 in 9 twist barrel. Haven't compared it to a 10/22 at longer ranges but I suspect the dedicated rifle would give better results further out. Eventually I'll build or buy a 22lr upper but this works for me for now.

What are your trade interests?

dmatzinger · Oct 21, 2021

i am trying to build a dedicated 22 lr upper, so right now, really just a dedicated 22 lr ar barrel with the collar and bolt,
but PM me what your thinking,

Collar can be found here:

RTB 22LR barrel Collar Assembly SS

Use this collar to convert your drop in conversion kit to a dedicated bolt group. Collar assembly is designed to interface with CMMG and RTB .22lr dedicated barrels

Thanks,
But i need the one for CMMG. I spoke to RTB arms, and thes said with their bolt you can use either but with CMMG needs to be the CMMG colloar, and they are out of stock on that

Interesting that their bolt can use either collar, but the CMMG bolt will only work with a CMMG collar. Good info and GLWS.

Is this the standard .223 to .22 conversion kit or another caliber? The link you posted is for a other caliber. I have one of these and I love it in my dedicated. 22 upper, was thinking about getting a spare.
