Colts HBAR A2 Sporter

[RCS]

The first Colt Heavy barrel was the Colt 606 with four different upper configurations and with the early 1 in 12 twist. The buffer was solid plastic (I think)

Got my upper in the late 90's as dealers were importing only the upper as the full auto lower had to remain in CanadaAttachment 107238Attachment 107239Attachment 107240
