Roughly 200 rounds of combined bird and buckshot were shot with the buffer mounted.
"Fits Shotguns/Rifles w/ AR-15 collapsable stock adapters that do not use the actual AR-10/AR-15 operating system
Fits Mil-Spec dimension collapsible stocks
Allows a collapsible stock on your tactical rifle or shotgun
Hydraulic recoil reducer that is extremely effective and actually reduces felt recoil over 50% (we've tried it and it works)
Well built with extremely long service life"


Alternatively, for $120 PayPal (buyer pays fees) I'll sell it with a Magpul CTR in FDE (Mil-spec).
