A firearm barrel tray having a barrel channel and a firearm accessory mounting interface, wherein the firearm barrel tray is configured to be attached to a firearm stock such that the barrel channel sits on a first side of the firearm stock and the firearm accessory mounting interface is configured to align with a recess on a second side of the firearm stock.

A method for making an object (e.g., a projectile) includes preparing a premixture of a first metal powder having a first particle size, a second metal powder having a second particle size, and a polymer binder; compressing the premixture in a mold at a pressure of about 75 psi to about 500 psi and a temperature of about 15 C. to about 40 C. to form a projectile preform; and heating the projectile preform at a temperature of about 80 C. to about 350 C. for about 0.5 minutes to about 30 minutes. The polymer binder may include a dry powder coat. The object may have a density between 1 and 4 g/cm.sup.3.

A firearm holster and a method of making the firearm holster is disclosed. The firearm is wholly or partially molded of ballistic material in such a way that a bullet that is discharged into the holster is retained within the holster or deflected so that it doesn't cause damage to the user of the firearm or other persons or property.

A firearm barrel tray having a barrel channel and a firearm accessory mounting interface, wherein the firearm barrel tray is configured to be attached to a firearm stock such that the barrel channel sits on a first side of the firearm stock and the firearm accessory mounting interface is configured to align with a recess on a second side of the firearm stock.

A method is described of making a training firearm that has a replaceable magazine. The training firearm is not an actual firearm but possesses a visual look and tactile fee of an actual firearm, to enable a user to train realistically but safely.

Threaded metal inserts for polymer lower receivers and hybrid polymer lower receivers comprising one or more of such inserts, as well as kits and methods therefor are disclosed. A threaded metal insert has a substantially circular aperture configured with screw threads to releasably yet connectively interface with a separate traditionally threaded firearm component such as a buffer tube or a pistol grip screw. Inserts can be any overall shape so long as it can be integrally embedded within a traditionally threaded portion of a polymer lower receiver in a way that does not interfere with normal operation of an assembled firearm and leaves exposed the internal threading of the insert. Inserts can also comprise textural features on the exterior surface configured to permanently interface with and embed the an insert into molded polymer. A hybrid polymer and metal lower receiver is a stripped polymer lower receiver for an AR type firearm, such as the AR-15 or AR-10, having one or more such threaded metal inserts at least partially embedded in a portion thereof.

A method is disclosed for coating a projectile for use in an ammunition cartridge. A polymer jacket is applied to an undersized projectile core of a first standard caliber to bring the outer dimensions of the jacketed projectile into compliance with those of a second, larger caliber projectile. The polymer jacket coating may produce a non-uniform outer diameter of the polymer jacketed projectile and may include a plurality of circular cavities defined therein. The polymer-jacketed projectile may be a bullet for pistol or rifle ammunition, or a pellet, or shot for use in a shotgun shell.

A one-piece gunstock for firearm and the relevant manufacturing method are described, said one-piece gunstock being composed of a frame (1) having two half-shells (1a, 1b) extended longitudinally and defining a recess inside the frame (1), a plurality of seats (31,32) and a space (42) for housing respective mechanical components formed between said half-shells and delimited by a transversal structural connection element (33) of said half-shells (1a, 1b), characterized in that said half-shells (1a, 1b) and said transversal connection element (33) are made in a single piece of an advanced composite material by a vacuum-bag moulding technology.

A sabot petal is described herein comprising a plurality of woven axial and undulated fibers angled to transfer setback loads. In some cases, the petal is a one-piece component configured to be positioned around a long rod projectile or other aerostructures or aeroshell shapes to be launched with in a gun bore, or rocket or missile launch tube. Corresponding systems and methods are also disclosed.

Manufacturing a gun stock core using a curable material in a mold that includes a plurality of mold sections wherein each mold section defines a portion of a mold cavity of the mold. A first amount of curable material is poured into the mold cavity portion of the first mold section and cured to form a first portion of the gun stock core. A second amount of curable material is poured into the mold cavity portion of the second mold section, wherein the second mold cavity portion is fluidly connected to the first mold cavity portion to enable a bond to form between the poured material in the first and second mold cavity portions and cured for a predetermined time period to form a second portion of the gun stock core. The finished gun stock core has a variable specific gravity, weight, or strength along a longitudinal length and height.
