Abstract

Embodiments of the present invention provide significant firearm recoil force reduction and can be integrated within a traditional firearm stock. Such recoil shock absorbers include a body assembly, plunger assembly, and return spring. The body assembly includes a shock tube, cylinder end, and accumulator. The shock tube includes an opening at its distal end, the cylinder end is rotatably coupled to the shock tube, and the accumulator is coupled to the cylinder end. The cylinder end can be selectably/adjustably aligned with the shock tube opening, resulting in a selectable/adjustable orifice and a pathway from the shock tube to the accumulator. The plunger assembly is slidably coupled to the body assembly and includes a piston. The piston and the shock tube are in slideable relation such that when the plunger assembly is introduced into the body assembly the piston is introduced into the shock tube.

Dependent claims

A recoil shock absorber for a firearm, the recoil shock absorber comprising:

a body assembly configured to be installed in a stock of the firearm, the body assembly including:
a shock tube including an opening at a distal end;
a cylinder end rotatably coupled to the shock tube at the distal end of the shock tube, the cylinder end including a tapered protrusion configured to be adjustably aligned with the shock tube opening;
and
an accumulator chamber coupled to the cylinder end, the shock tube arranged on a first side of the cylinder end and the accumulator chamber arranged on a second side of the cylinder end, opposite the first side, alignment of the shock tube opening with a part of the tapered protrusion forms a resulting orifice and pathway from the shock tube, through the cylinder end, and to the accumulator chamber;
a plunger assembly slidably coupled to the body assembly, the plunger assembly including a piston at a proximal end of the shock tube, the piston and the shock tube being in slideable relation such that when the plunger assembly is introduced into the body assembly the piston is introduced into the shock tube;
and
a return spring coupled to the piston and the shock tube.
