I picked up a cmmg .22 conversion for my ar15 and I'm having problems with it. What's happening is when I fire the rifle it chambers another round but does not let me fire again. Any one else have this problem?
take it out and lube it up good , make sure it slides back freely by hand without hanging up , make sure its not got adverse wear on it some where as it might be hanging up . I have roughly somewhere between 4500-5000 rds thru mine and all I had to change a bad extractor out but CMMG thought maybe it was bad/ Chipped from the start and replaced it no questions asked .
If that doesnt fix it start taking pics and posting them up here so we can take a look at it
