I have a CMMG .22 conv in an AR pistol right now , I'm using a standard 7 inch AR barrel and the gas port is clogging with lead and powder residue maybe 1200 rounds out of it

can you use a dedicated .22 barrel with this 22 conversion, or was it designed for regular AR barrels ??


or do they sell a .22 pistol barrel in 7 or 10 inch that does not have a gas port hole drilled ??

other that cleaning it often whats the fix

Most .22 AR barrels such as Taccom and CMMG will come with a "collar".
You just snap out the chamber adapter and replace it with the collar.

Most guys who use a drop in kit will throw a standard BCG in their rifle at the end of a range session and run a few rounds of 5.56 through it to clear the gas system.

clear the gas system back into the action where the 22 conversion sits ?? sounds like you're just recirculating the debris ?? but without a gas port hole it would just blow them out the muzzle ??

is this safe to do so , I wouldn't think so

They recirculate the debris out of the GAS system into the receiver, yes.  Then they CLEAN the rifle before putting the 22 conversion back in.  Crazy, I know.
