Aug 6, 2019 #7 G grimnar15 Ultimate Member MDS Supporter Jul 21, 2019 1,645 Cool --- or since I have several Colts I can sell the 6721 And build a brand new pistol 300BO.

Aug 10, 2019 #10 3paul10 Ultimate Member MDS Supporter Mar 6, 2012 4,904 Western Maryland exactly as the others have said...leave her alone, and get another upper.... Be careful switching back and forth from 5.56 to 300, easy to make a mistake and blow her up...
