Impeccable machining by Freeman, Verified Owner, June 3, 2026
When I say this brake has probably some of the nicest machining I have seen in my life I mean it. Nothing but excellence from these guys. Works flawlessly. Keeps my shots smooth and under control. When paired with the pyro it’s a BLAST to shoot!
