    Just bought this and the rubber on the back is in 2 pieces completely broken. Also it has D139 scratched in 3 inch block letters on the left side. I get that it is used but mine was not what I paid for and in poor condition.

    Came in great condition, and these Colt tubes are unmatched. They are so smooth that the action sounds much more quiet than with cheap extensions.
