Terrible mounting design

by P, from LA, United States Written on October 25, 2025
This thing is garbage. Filed on it all day very carefully so it'll fit and no success. There's not enough plastic on the part that mounts to the receiver after filing down for fitment.it uses a tiny plastic wedge on a screw that expands your receiver out to hold itself in place with pressure. Spend the money and get yourself a mil spec buttstock. Thowing this thing in the trash.

Its very well built and I really like the recoil reducing spring action. The FAB Defense Core-CP stock comes with adapters for commercial or mil-spec tubes so fitment was not an issue.
