Abstract: A grenade firing mechanism (12) includes a body (24) containing a firing pin (20) and a tiring pin actuator mechanism (22). A safety system includes twist to arm collar (70) and a safety interlock (92). The collar is movable between an unarmed position and an armed position and tire safety interlock is movable between a collar locking position, a collar release position and a firing position. When the collar (70) is in the unarmed position and the safety interlock (92) is in the collar locking position, actuation of the firing pin (20) is inhibited and the safety interlock (92) inhibits movement of the collar to the armed position. When, the safety interlock (92) is in the collar release position, the collar (70) is able to be moved between said unarmed and armed positions and actuation of the firing pin is inhibited. When the collar (70) is in the armed position and the -safety interlock (92) is in the firing position, actuation of the firing pin is enabled.

The trigger guard assemblies also include a post that engages the trigger guard, and is movable in relation to the trigger guard between a retracted position and an extended position. When in the retracted position, the post does not interfere with movement of the trigger guard between the open and closed positions. When in the extended position, the post interferes with movement of the trigger guard between the open and closed positions, and exerts a lateral force on the firearm to further secure the trigger guard to the firearm.

Abstract: A ballistic armor system comprising a metal strike face plate, a laminate composite backing material secured to the metal strike face plate and an air space provided between the metal strike face plate and the laminate composite backing material. The metal strike face plate has a predetermined defined thickness and has a plurality of slotted holes set at an oblique angle relative to the vertical orientation or axis of the metal strike face plate. The plurality of slotted holes is sufficiently small to prevent the passage of a projectile or fragment therethrough. The laminate composite backing material comprises at least one material selected from an aramid fiber material, S-glass, E-glass and UHMWPE, and is provided in combination with a polymer-based resin material. The air space provided between the metal strike face plate and the composite backing material has a depth in the range between 0-10 inches.

Abstract: A recoil reducer device for use with a firearm is provided comprising a heavy weighted doughnut situated in a cylinder which is screwed onto the muzzle of the barrel. The exhaust gases as they exit the muzzle will enter the base of the cylinder through side portals and forcefully push the doughnut forward striking the base plate of the cylinder thereby pushing the recoil reducer device forward considerably reducing the recoil force generated by the fired bullet. A spring inside the cylinder will push back the weighted doughnut to its original position.

Abstract: Disclosed herein is sabot for a sub-caliber projectile comprising a plurality of petals, such that a slip mechanism can be incorporated between the sabot petals and the pusher mechanism to decrease or prevent the sabot from rotating in a rifled gun bore, or the petals themselves can be separated into forward petals and aft petals, with only the aft petals rotating along with the gun rifle. When separate forward petals and aft petals are used, the torque transferred to the forward petals is greatly reduced, thus decreasing the angular rotation of the forward petals with the intent of preventing the forward petals from rotating. The slip mechanism has slip plates with low-coefficient of friction surfaces configured to contact adjacent slip plates prior to and during launch. As assembly, a system, and corresponding methods also are disclosed.
