When the payload and the guidance kit are mechanically connected with one another and electrically connected with one another, the payload and the guidance kit are angularly aligned at a same clock position measured relative to the longitudinal axis or angularly displaced at different clock positions measured relative to the longitudinal axis.

Abstract: A takedown firearm that may utilize removable barrels of different calibers. The disclosed firearm does not require a barrel extension, instead providing positioning of the barrel that is sufficiently precise and repeatable. Tensioning of the barrel is provided passively during installation of the removable barrel, without need for adjustment or additional tightening. Securing the removable barrel to the receiver does not structurally involve the fore end, thereby avoiding harmonics effects associated with fore end interfaces to the receiver. The firearm takes advantage of an “underspaced” chamber arrangement to provide additional tolerance for manufacturing and assembly of the firearm.

Abstract: A recoil damping system includes at least one easily attached and detached spring tube of variable stiffness, absorbing the severe recoil created in firearms firing heavy-weight cartridges with high gas pressure. In the system in question, the spring tubes absorb the severe recoil that is created in firearms firing heavy-weight cartridges with high gas pressure in contrast to the known technique, and hence the impact on the shooter's shoulder is minimized. Thus, after the shot, the pain and injuries suffered by the shooter due to severe recoil are not in question any longer. The practical recoil damping system is compatible with all firearms firing heavy-weight cartridges with high gas pressure, where easily attached and detached spring tubes with variable stiffness can be applied.

Abstract: A forward-fighting ballistic shield device is provided. The device is comprised of a ballistic shield device that can function as both a ground-deployed and a carried shield to protect against ballistic blast and fragmentation impacts. The device comprises an aluminum frame attached to a ballistic panel with a polyurethane coating, along with an adjustable telescopic leg secured by a locking mechanism for stability when deployed. A tether further ensures the leg maintains the desired angle, while a fastener secures it parallel to the frame when carried. Additionally, deployable straps with grommets enable staking the device to the ground for enhanced stability. The device further features a rapidly inflatable ballistic panel with an inflatable bladder, capable of being manually or gas-inflated via a canister. The bladder may be reinforced with tensile members or foam-core and absorbs and distributes impact forces.
