Firearm recoil modifying device

A firearm Comprising:

• a barrel having a muzzle;
• a recoil modifying device coupled to the firearm barrel at the muzzle, the 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 removably coupled 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.

A method of modifying recoil of a firearm comprising the steps of:

• providing a firearm having a barrel with a muzzle;
• providing 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, 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.;
• attaching the rearward end of the adapter to the barrel at the muzzle;
• firing the firearm to generate combustion gasses with a force which is less than the maximum level at which energy is stored by the biasing member and move the piston from the rearward position to the forward position;
• and
• moving the piston from the forward position to the rearward position with the biasing member.
