I have for sale (1) Bushmaster ACR 12.5" barrel. Started out life as a standard 16" barrel. Cut and threaded (1/2 x 28) by ADCO. About 400 total rounds on this barrel. It was engraved with my trust info, has been blued over, but is still visible. You can't see it with the handguards on anyway. I can take more pics if necessary.
Asking $250 shipped.
