For a while AR15Performance offered to do custom XCR bbls for $550 but you had to supply the bbl extensions from RA. I don't think they are willing to do them anymore....or they may not even be in business.I’m sure this has been discussed before but I never found it. Does anyone know the current source for XCR barrels? Are they all from one other company or are there various sources?
Has any third party ever tried to offer a conversion, the way DWilson converts other AR barrels for use with LMT’s monolithic rail platform?
