Abstract
An improved recoil reduction system comprises a forward body, a friction spring, a rear body, a bolt, and, optionally, a bumper. When in forward battery, the said friction spring is compressed to a preloaded operating point by the bolt. In embodiments, when a weapon equipped with the improved recoil reduction system is fired, the front body is impacted by the bolt carrier group of the weapon and the rear body moves aft and strikes the rear of the shoulder stock of the weapon, compressing the friction spring. During compression, the tapered mating surfaces of the friction spring generate friction and thereby dissipate the energy generated from firing the weapon in the form of heat, thus reducing the felt recoil of the weapon.
Claims11
A recoil reduction device, comprising:
- a forward body;
- a rear body;
- a bolt fixedly attached to said forward body and movably attached to said rear body;
- and
- a friction spring compressed between said forward body and said rear body by attachment of said forward body and said rear body to opposite ends of said bolt, wherein said bolt passes between said forward body and said rear body through an interior of said friction spring;
- wherein said forward body further comprises an interior cavity sized to house a cylindrical weight, and further comprising a cylindrical weight housed within said interior cavity;
- and
- wherein a number of coils in said friction spring is calibrated to optimize a desired recoil force of a weapon in which said recoil reduction device is installed.
A recoil reduction device, comprising:
- a forward body;
- a rear body;
- a bolt fixedly attached to said forward body and movably attached to said rear body;
- a friction spring compressed between said forward body and said rear body by attachment of said forward body and said rear body to opposite ends of said bolt, wherein said bolt passes between said forward body and said rear body through an interior of said friction spring;
- and
- a buffer at least partially enclosed within a second end of said rear body, wherein said buffer and said rear body both include a retaining pin aperture sized for receiving a retaining pin, the retaining pin aperture of said buffer being located to align with the retaining pin aperture of said rear body when said device is assembled;
- wherein a number of coils in said friction spring is calibrated to optimize a desired recoil force of a weapon in which said recoil reduction device is installed.
