RECOIL REDUCTION SYSTEM FOR FIREARM

摘要

A user-adjustable recoil reduction system for a firearm includes a buttstock and a butt pad assembly movably mounted to the buttstock. A spring is disposed in the buttstock which is acted on by opposing front and rear spring guides. A preload adjustment screw is rotatably coupled to the butt pad assembly which engages the rear spring guide. Rotating the screw in opposing directions alternatingly advances or retracts the rear spring guide in the buttstock. Advancing the rear spring guide compresses the spring to set a first spring preload condition and retracting the rear spring guide relaxes the spring to set a second spring preload condition different than the first condition. The spring preload conditions may be selected to match firing light or heavy type ammunition shell loads. In one embodiment, the adjustment screw is accessible for adjusting the preload without removing the butt pad assembly from the buttstock.

主权项

1. An adjustable recoil reduction system for a firearm, the system comprising:
an axially extending buttstock having a longitudinal stock axis, a rear end, a front end, and a longitudinally extending internal cavity; a ram including a cantilevered mounting extension, the mounting extension projecting forward from the ram through the rear end of the buttstock into the internal cavity, the mounting extension slideably coupling the ram to the buttstock; a butt pad coupled to the ram; an adjustable plunger assembly comprising a rear spring guide disposed in the buttstock and a preload adjustment screw rotatably coupled to the ram and engaging the rear spring guide, the plunger assembly being movable forward and rearward in the buttstock; and a first compression spring mounted inside the buttstock and engaged by the rear spring guide, the plunger assembly operating to compress the first compression spring when the buttstock moves rearward relative to the plunger assembly; wherein rotating the adjustment screw in a first direction advances the rear spring guide and compresses the first compression spring for setting a first preload condition, and rotating the adjustment screw in an opposite second direction retracts the rear spring guide and allows the first compression spring to expand for setting a second preload condition; wherein when a rearward acting recoil force is generated by discharging the firearm, the buttstock moves rearward and compresses the first compression spring against the plunger assembly to absorb at least a portion of the recoil force.
