Wobble-free when folded outThe SpecOps folding stock offers compact storage and the ability to reduce perceived recoil by as much as 65%, even with the stock folded. The rubber coated wire-frame stock incorporates a rubber butt pad and is easy to fold over the top of the receiver for storage or transport. Recoil reduction is accomplished via the heavy spring within the pistol grip that is connected to, and provides resistance against, the shotgun receiver as it moves up and to the rear along an inclined surface during recoil. The receiver’s movement and spring’s resistance absorb a large amount of the recoil produced upon firing, meaning the shooter experiences significantly less unpleasantness.
