The device provides a durable, modular interface for attaching muzzle accessories and additional mounted components in a versatile assembly.

Abstract: Described herein are multi-part projectiles that include a high-friction coating as part of an interface between parts of the projectile body. The high-friction coating reduces the probability that projectile parts coupled at the interface would rotate relative as the projectile is launched, thus enhancing the reliability and accuracy of the projectile. In one example, a multi-part projectile includes a projectile body having first and back sections coupled by an interface. The front section has a front land and the back section has a back land. The threaded interface restrains the rotation of the projectile body first and back sections. A high-friction coating is disposed on at least one of the lands of one or both the front and back sections. The high-friction coating has a co-efficient of friction greater than the parent metals against each other alone, without the high-friction coating disposed therebetween.

Abstract: A shotgun balancer for use in a double barreled shotgun. The balancer can be inserted into a barrel that is not to be loaded with a shell and thus can be used to help attain a comfortable balance of the shotgun. In addition, adding a weight to a gun helps reduce the recoil felt by the shooter. The shotgun balancer can also be used as a training aid, as by increasing the weight of the shotgun a user can build up strength in his/her relevant muscles. Once the weight is removed, the user will find that the shotgun is easier to lift, move and swing. The balancer can have a rod and one or more adjustable weights which can slide along the rod in order to adjust the weight distribution of the balancer.

Abstract: Embodiments of the disclosure relate to adjustable stocks for firearms and methods for installing an independently sprung tensioning mechanism. The adjustable stock comprises a stock body attached to a buffer tube, with a lever-operated tensioning mechanism. The mechanism includes a tensioning block with fins to grip the buffer tube, an indexing pin, and a retaining pin. When the lever is depressed, the tensioning block and indexing pin disengage, allowing longitudinal adjustment of the stock on the buffer tube. The tensioning block applies upward pressure on the tube, compensating for rotational tolerances during assembly. Both the tensioning block and indexing pin move independently when engaging with the buffer tube but move together when disengaging. The indexing pin is biased towards the buffer tube by a spring, while another spring biases the tensioning block. The lever engages the retaining pin to retract both the indexing pin and tensioning block.

Abstract: A cylindrical machine gun ammunition carrier drum device with hand crank and spindle, which allows operator to regulate belt-fed ammunition at a proper cyclic rate of fire and reload linked ammunition in an efficient, accelerated manner. This retract and release belt-fed ammunition method would provide proper tension and uniformity to the linked rounds, preventing the weapon from malfunctioning and improve cyclic dispersion of ammunition. This method applies to all calibers of belt-fed personal and crew-served automatic weapons. The external hand crank and internal spindle would work in unison to recover the belt if it is yanked from the cylindrical drum container prematurely. A flexible warning device ribbon connected by ammunition links would ensure all rounds are expended from within the drum when abridged from spindle to belt. Additionally, this internal warning device can be linked between belts at operator's preference.
