Rifle (1) comprises barrel (2) and loading means (15) for introducing a projectile from magazine (7) into breech (4). The projectile is propelled by a compressed gas propellant initially stored as a liquid in canister (10). The liquid is heated to a super critical state in chamber (8) by heating element (12) to induce a phase change such that the liquid becomes a highly dense gas. The phase change from liquid to gas provides the energy required to expel the projectile at high velocity from rifle (1), regardless of the ambient temperature. The propellant is preferably CO2 which is heated to 31.06° C. Rifle (1) produces minimal noise and no heat signature, making it suitable for military and stealth purposes. A pistol and launchers for grenades or mortar bombs are also disclosed. Another version can launch low earth orbit satellites or payloads.

The present invention overcomes the limitations of the prior art by providing a centerfire rifle cartridge with a case having a head having a rim, a body extending from the head to a tapered shoulder, and a neck extending from the shoulder and defining a mouth receiving a bullet. The body has a straight external surface free of a protruding belt, and has a maximum diameter sized to closely fit for operation within a standard action of magnum width. The cartridge has an overall length sized to closely fit for operation within a standard action such as a short action or a long action.

A rifle having a receiver with an integral hand guard and a barrel. The barrel is connected to the receiver. The hand guard extends over and surrounds the barrel. A removable hand guard is attached to the receiver by an attachment that stably holds the removable hand guard to the receiver. The attachment is arranged for allowing detachment and removal of the removable hand guard from the receiver without removal of fasteners.

The present invention is a modular gunstock utilizing a two-piece mounting structure and a stock module. The structure comprises a weapon attachment, in the case of an AR15 / M16 rifle a receiver extension tube, and a sleeve slidable over said attachment and containing mounting structure for the stock module. The disclosed stock module is adjustable for length and features a length pre-set system, a latch with independent dual-pawls and an integrated impact buffer, modular tailpiece, and storage. The sleeve also features a position selectable fixed cheek plate.

The present invention is a modular stock system for rifles. The system replaces the rifle's buffer tube with a modified one containing a mount for a constant cheek weld and a rail track for adjustment. A stock module then mounts on the replacement buffer tube. The stock module is interchangeable depending on the user's needs. Various configurations of the stock module are discussed, including adjustable stocks, fixed stocks, and specialized stocks. The stock module may be made even further modular by the addition of rail system.

A grip and bipod mounting device for mounting a bipod supporting grip assembly to a “picatinny” mounting rail structure as are often affixed below the forearm stock of a firearm such as a military rifle (e.g., as per standard MIL-STD-1913). In particular, the present invention is directed to mounting a Parker-Hale style of firearm bipod on a bipod supporting grip assembly including a contoured mounting block segment inletted to cover and attach to a picatinny rail affixed beneath the forearm stock of the firearm. A grip or handle depends transversely from the mounting block segment and has a plurality of evenly spaced circumferential band-shaped outwardly projecting surface features. The bipod supporting grip assembly is releasably attachable to a bipod frame by means of a quick release connector such as a bayonet lock or similar locking means. The bipod frame includes a pair of extensible / retractable legs, each having a pair of telescoping sections to enable the height of the bipod to be adjustable as desired.

An automatic or semiautomatic blackrifle type rifle having a receiver and a bolt carrier movably coupled to the receiver. An action system is connected to the bolt carrier for cycling the bolt carrier in the receiver. A folding butt stock is connected to the receiver, the folding butt stock being both foldable and collapsible.
