Patent ID: 8910558

Claim:
A firearm recoil modifying device Comprising: a cylindrical body having a rearward end, a forward end, and a longitudinal axis extending therebetween, the cylindrical body defining an interior volume; an adapter, having a rearward end for coupling to a muzzle of a firearm and a central aperture aligned with the longitudinal axis, the adapter coupled to the rearward end of the cylindrical body; an end cap coupled to the forward end of the cylindrical body, the end cap includes a central aperture aligned with the central aperture of the adapter along the longitudinal axis; a piston carried within the interior volume of the cylindrical body for reciprocal movement between a rearward position and a forward position, the piston includes a rearward end, a forward end, and a central aperture extending therethrough from the rearward end to the forward end and aligned with the central apertures of the adapter and the end cap, along the longitudinal axis; and a biasing member capable of storing energy at a maximum level during movement of the piston to the forward position and releasing the stored energy to bias the piston to the rearward position, resulting in an impact between the piston and the adapter, the piston moved from the rearward position to the forward position by a force generated by expanding gasses, the force generated by expanding gasses is less than the maximum energy storage level of the biasing member, preventing impact of the piston with the end cap.
