maydog Posted November 21, 2014 Share Posted November 21, 2014 I have an older M190 that the bolt will close and rotate fine without a shell in the chamber but will not rotate with a shell unless I force it with my hand. I stripped it down reassembled and it is still doing it. Quote Link to comment Share on other sites More sharing options...
Benelligunny Posted November 23, 2014 Share Posted November 23, 2014 1. Check the extractor cut on the barrel for any burrs/gouges, carefully remove them with a small file if necessary. 2. Check extractor for wear or roughness. Replace if necessary. 3. Oil the recoil assembly, bolt and bolt rails. Try these first then get back to me if this doesn't work.

truckcop Posted November 23, 2014 Share Posted November 23, 2014 Quick note: you are letting the bolt go forward under it's own power rather than riding it forward with your hand, right? Quote Link to comment Share on other sites More sharing options...
