I have a new upper on my bushmaster , changed the upper to a 24in heavy barrel 1/9 chrome lined . Also has a new bolt and carrier . Only 6 rounds have gone though for the break in . I also have a brand new DSA 1/7 chrome lined 16" upper no bolt or charging handle . The DSA upper has never had a round in it . Would like to sell both for $1150 or will separate . Bushmaster rifle with scope and clips $850 and the DSA for $300 . I had trouble with pics uploading from iPad so if interested I can send pics in email or answer questions .
