I was searching for a way to keep my replica 652/3 builds legal while using the correct leingth barrel. This brake fit the profile and look of the A1 barrel. Only draw back... If there is one is there is no pre fabricated hole for pinning the unit to a barrel, it must be drilled. Material and finish are excellent so I would.not hesitate to use them again.
