Is there anything for a bushmaster mpw inner outer barrel every time I shoot mines the bbs shoot every were it feels like the bb doesnt have support to leave the barrel
No. There is no barrel replacement kit for the Bushmaster. You do have a 1 year warranty thru Crosman. Contact them about the issue.
