SilencerCo 17-4 stainless steel piston mount for Hybrid suppressors has noticeable recoil reduction when mounted. Blast to the sides is real but groups are tighter with the can attached. Steel construction holds up to high pressure.
17-4 stainless piston mount for a silencerco hybrid suppressor. mount threads were correctly cut, ratchet detent engages positive. blast to the sides indoors is rough as expected from a 5.56 piston system, but recoil reduction is what i bought it for
