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.
