US12736303 - Stock for a firearm and method of manufacturing a stock for a firearm

A stock for a firearm. The stock includes a foam core, a carbon fiber skin and a carbon fiber insert having a housing for housing the action mechanisms of the firearm. The carbon fiber insert includes a sheet molding compound (SMC) or a bulk molding compound (BMC) that includes a resin matrix and randomly arranged chopped carbon fibers in the resin matrix. The foam core has a cavity in which the carbon fiber insert is housed. The carbon fiber skin covers the foam core and at least part of the carbon fiber insert housed in its cavity, the carbon fiber insert being mechanically bonded to the carbon fiber skin.

US12704360 - Carbon fiber ammunition casing

A carbon fiber reinforced ammunition casing consists of a singular piece or two complementary longitudinal half sections coupled together. The half sections are formed with radial edges having complementary tongues and grooves to allow coupling of the half sections to complete the casing. A weld is applied along each seam where the half sections couple together and excess weld material is removed by press proofing. Each singular piece or half section is formed by injection molding or additive manufacturing of a mixture of carbon fiber and polymer.

US12618628 - Forged carbon fiber rifle barrel

A method of forming a carbon fiber rifle barrel may include the steps of heating a barrel core to increase the length of the barrel, placing the barrel core inside a mold and holding the lengthened barrel in place, adding a carbon fiber mix to the mold in which the carbon fiber mix includes a blend of resin and chopped carbon fibers, sealing the mold, curing the carbon fiber mix surrounding the lengthened barrel core in which the cured carbon fiber mix holds the length of the barrel core creating a tension on the cooled barrel core which increases a rigidity of the rifle barrel thereby increasing the accuracy of the rifle barrel, removing the rifle barrel from the mold, and finishing the rifle barrel via grinding to a desired finish.
