Not all CMMG Stainless Steel .22 Conversion Kit are made the same. Both are lubed.
As with any machined part there are tolerances. Or the rails could be tweaked outward. Have the units been taken apart yet?
I have 3 now and they all drop in with a snug fit in the chamber.
I now have 4 and they all work great. As shadowcop said there are tolerances and other possibilities that can
cause issues. I have a lot of options for installing a conversion. It may fit one rifle perfect and it may be a very
sloppy fit or a very tight fit in another. Once I have them running as well as they're gonna get, I don't change them
I don't ever disassemble them for cleaning. OP have taken these bolts apart for every cleaning, it eventually takes
it's toll on the bolt.
I honestly believe CMMG fires every bolt that goes out the door... That's a big step to eliminate problems for the
The CMMG .22 conversion is designed to be a simple plug and play unit. All kits are tuned from the factory and do not require any modification.
Whatever happen to SIMPLE PLUG AND PLAY.
