I have a Bushmaster 20" chrome lined 1/7-govt profile barrel. A3 upper by CMT (Continental Machine and Tool) with white T markings. Assembled upper ready to attach to your lower. Taken to the range once, no scratches only small marks in the fsb. B/C/CH included. Only thing missing is the handguards (sold them a while ago).
Will sell for $450 shipped or will trade FTF (Ft. Worth) for a bolt action LH .308, 10/22T model or a MkII 10/45 plus cash.
Lower not included.
