An adjustable firearm butt assembly comprises a base plate selectively attached to a buttstock of a firearm. The base plate has a base slot. An adjustment nut is aligned with, and transversely movable relative to, the base slot. A pad plate is selectively attached to the base plate with the base plate being interposed longitudinally between the pad plate and the adjustment nut. The pad plate has a plate slot and a guide track. The plate slot is aligned with both the adjustment nut and the base slot. A guide pin has a portion selectively received in the guide track. An attachment fastener selectively extends through the plate slot and into engagement with the adjustment nut to selectively attach the pad plate to the base plate. The attachment fastener is laterally movable with respect to the plate slot. The attachment fastener is selectively movable between unclamped and clamped conditions.

An adjustable comb riser has an elongated stock profile that protrudes above the factory firearm or non-firearm stock, a rear face that clamps between the factory stock backplate and factory recoil pad, using the recoil pad screw holes in the stock backplate without modification. The rear face includes slots that will allow the riser to adjust vertically up and down in order to give the shooter a proper cheek rest on the firearm or non-firearm.

A Self-adjusting Gunstock Recoil Pad comprises of an intermediary mounting plate with individually movable segments bearing against a ring. The elastic ring is forced outwards by each segment, and provides a field-adjustable external contour matching individual variations in profile of gun-to-recoil-pad interfaces. A recess in the plate holds a wedge captive by a pin through a slot in the wedge, the wedge when inserted engages bosses protruding from the pad into a receiver and forms an attachment between the gun and pad which is reversible by use of a hook shaped wrench applied to a receiving profile in the plate, the profile guides the action of the wrench in pulling the wedge out. The plate is assembled from two layers to confine the wedge as an assembly by use of tabs in one layer engaging interference-fit cut-outs in the other layer.

An improved buttstock for a firearm is disclosed, the buttstock comprising a comb, the comb comprising an indexing surface on a comb extension, the comb extension being configured to move between an expanded configuration and a retracted configuration; a buttstock, the buttstock comprising a buttpad extension indexing surface, the buttstock being configured to move between an expanded configuration and a retracted configuration. A common lock can secure both the comb extension and the buttpad extension in a fixed position. The common lock can release one or both of the comb extension and the buttpad extension to slide with respect to the body of the stock.

A buffer tube apparatus for a weapon includes an outer tube defining a longitudinal axis, the outer tube having a first end configured to be coupled to the weapon and a second end opposite the first end, the second end configured to be coupled to a stock. A buffer assembly includes a shock absorber and is disposed within the outer tube. The buffer assembly is configured to absorb an impact of recoil generated by the weapon. An adjustment bar is configured to interact with the stock. The adjustment bar is coupled to the buffer assembly and slidable with respect to the outer tube along the longitudinal axis.

A recoil reduction system for a firearm. In some embodiments, the recoil reduction system includes a biasing element and a butt pad assembly configured to deform substantially proportionate to each other during a recoil event. The biasing element and/or butt pad assembly may include a spring-type element or, alternatively, a dampening device. The butt pad assembly may include an open cell butt pad having a hardness that is substantially higher than conventional butt pads.

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.
