The invention provides a barrel flexing mitigation assembly (10), which is suitable for reducing barrel deflection, particularly in long range rifle barrels, such as those used in target shooting, hunting or sniper applications. The barrel flexing mitigation assembly (10) comprises a tubular shaft (20) extending coaxially with a rifle barrel (12) for defining an exoskeleton (20) within which at least part of the barrel (12) is encased; and a tubular barrel stabiliser (22) which is snug-fitted over the barrel (12), such that it is radially positioned between the barrel (12) and the tubular exoskeleton (20).

A modified AK-style rifle including a receiver body with a back end having a first threaded cylindrical cavity and a second cylindrical cavity located below the first threaded cylindrical cavity. A lower portion below the first threaded cylindrical cavity has a width that is narrower than the upper receiver section to allow for passage of a pair of parallel and opposing telescoping bars on each side. A trunnion is connected to the receiver front end and an ambidextrous bolt stop is attached to the receiver body. A removable stock is coupled to the first threaded cylindrical cavity. A first bolt carrier rail is attached to a first side wall of the receiver body and a second bolt carrier rail is attached to a second side wall of the receiver body. A bolt carrier slidingly bears on the first bolt carrier rail and the second bolt carrier rail. A gas block includes a short stroke gas piston aligned with the bolt carrier section.

A compact shotgun, a trigger assembly that could be used with such compact shotgun or other firearms, and an adapter and multipurpose mount that could be used with firearms or other devices are all disclosed. Each element has separate utility and combined utility in forming a combined under-mounted shotgun and long gun assembly.

A conversion kit for a handgun is particularly suitable for converting a pistol into a pistol carbine. There is described the implementation of such a conversion kit, a conversion method and also a handgun that is converted in this way. The conversion kit for the handgun includes a housing. The housing is configured for establishing a connection to a frame of the handgun and for this purpose it has a linear guide for receiving the handgun frame.

The invention relates to the hand-held firearm and is the firearm having a shorter length compared to systems in which the magazine is located in front of the trigger guard.

The reduction in length is achieved by placing the magazine above the trigger guard.

In this case, the offset of the magazine from the longitudinal vertical plane allows to maintain the convenience of attaching the magazine.

The invention is aimed at reducing the size of the firearm while providing ease of loading, which improves the operational characteristics of the firearm.

A rotating bolt firearm may be configured to fire a .308 cartridge. However, the firearm may have a reduced weight in comparison to standard .308 rifles. The firearm may have many components typically used in a .223 rifle. The firearm may include a barrel extension with an extractor gap, which allows a .308 bolt to fit within a .223 sized barrel extension. The firearm may comprise an elongated magazine well in comparison to a .223 mil-spec rifle. The firearm may weigh less than 6.8 pounds with a 16 inch barrel, or less than 6.3 pounds with a 10.5 inch barrel.

Provided is a fast cycling/low recoil pistol caliber carbine assembly. The carbine assembly may include an upper receiver, a lower receiver, a feed ramp, a bolt stop, a magazine, a control mechanism comprising a control lever, a control base, a control pivot pin, and a control spring, an ejector, a gap filler member. The assembly provides last round bolt hold open, trigger finger actuated bolt release, short stroke cycle, barrel ramp, ambidextrous magazine release, and uses Glock magazines.
