The present disclosure generally is related to a modular chassis/stock system for a rifle type firearm that incorporates a recoil reduction assembly. The chassis/stock system includes a buttstock assembly that is configured to include an elongated housing for receiving a mounting body of the recoil reduction assembly.

A recoil buffer system having a buffer element with a buffer element body portion, a buffer element knob, and a buffer element cavity; a collar; a sleeve, wherein a sleeve recess is formed so as to accept at least a portion of the buffer element body portion therein; a buffer element recoil spring, wherein the buffer element recoil spring is positioned about at least a portion of the elongate buffer element body portion, between the collar and the sleeve; and a bumper, wherein a bumper extension portion extends from a first end of the bumper to a bumper shoulder, wherein the bumper extension portion is such that at least a portion of the bumper extension portion can be fitted at least partially within the sleeve aperture.

A recoil reduction system for a firearm. In some embodiments, the recoil reduction includes buffer tube housed within a buttstock, and a deformable structure for setting a clearance tolerance between the buffer tube and the buttstock to reduce lateral play while enabling smooth translation therebetween. In some embodiments, a guide pin and/or skid projections provide interference between the sliding components of the recoil reduction system when in a battery configuration, while releasing the interference during a recoil event.

A stock for a firearm. In some embodiments, the stock is configured for bi-directional folding to either side of a receiver of the firearm. In some embodiments, the stock is configured for length adjustment. A biasing element is provided for the length adjustment that biases a proximal (butt) subassembly of the stock against the shoulder of the user. The user can adjust the length of the stock by moving his or her shoulder fore and aft against the butt of the stock. The bi-directional folding and the shoulder length adjustment aspects may be incorporated into a single embodiment.

A cushioning and impact absorbing pad system with a surface layer of thickness t, and an elastomeric sub-surface structure of height h. The sub-surface structure comprises an array of elastomeric columns wherein each column has a frustoconical column wall surrounding a central void. The frustoconical column walls have a zone that is a more compressible, relatively collapsible zone in a region at an end of the column opposite the surface layer and a zone that is a relatively less compressible zone in a region at the end of the column abutting the surface layer. In other embodiments, pad thickness and column height are variable to create a surface which follows the contours of a human body.

Composite recoil-absorbing stocks for firearms are disclosed. One stock has a rigid body that has an internal cavity. A compressible insert may be positioned in the rigid body with an elongated front end that is narrower than a broadened rear end. The front end is positioned in a narrowed front end of the internal cavity, and the rear end is positioned in a wider rear end of the cavity. When the firearm recoils, the compressible insert can be positioned between the shooter and the rest of the firearm and can therefore dampen and absorb recoil forces. The positioning and size of the rigid body and compressible insert help prevent bending and buckling of the compressible insert, thereby limiting the effect that the compression of the insert has on aiming and accuracy of the shot. Other embodiments and related methods are also disclosed.
