You are most welcome. I have the CMMG on a 10.5 inch barrel gun. Lots of fun when I turn the gas off and insert the CMMG 22lr conversion kit. I find the Blackdog mags work flawlessly.

Do you like Blackdog .22LR mags better than CMMG mags? I've got three CMMG mags which seem to work pretty good for the most part, but the rifle produces a VERY annoying stoppage sometimes. A round will feed, but end up pinched (projectile end of the cartridge) in the TOP of the .22 bolt. You have to reach up through the mag well with a Leatherman tool (or pliers) and PULL hard... something I don't like doing to rimfire ammo!... OR... you have to split the rifle, pull the bolt and clear it.

Have you heard of this malfunction or experienced it? It seems to happen a LOT when the hi-cap mag is down to about three rounds remaining. I read that CMMGs charging handle FOR the .22 adapter could help. Thanks in advance. :-)
