US 2018/0023913 A1 · NON-SEGMENTED COMPOSITE BARREL FOR GAS OPERATED FIREARMS

Abstract

A method of making a continuous fiber barrel wrap sheath onto a steel riffled barrel liner of a gas-operated firearm is described. A wrap made up of composite fiber is wrapped onto a steel riffled barrel liner in a continuous fashion, with no interruption within the steel liner for the purpose of delivering high pressure gas through the steel liner. After joining the composite wrap to the steel barrel liner, either by mechanical or chemical procedure, a slot is formed by carving out a top and/or a bottom of the composite. A gas key insert is then placed in the made slots and retained by mechanical or chemical procedure. Finally, a gas port is drilled through the key insert.

A method of making a fiber wrapped firearm barrel utilizing a steel barrel liner;

the method comprising:
applying a corrosion resistant coating to a steel barrel liner insert;
wrapping a composite, further comprising fiber in a resin matrix, onto the steel barrel liner, over the corrosion resistant coating, thereby forming a composite structure of steel and fiber which contains fibers which are not interrupted by the circumference of the steel liner;
forming a at least one slot in the composite;
inserting a gas key into the at least one slot;
adhering the gas key to the steel barrel liner through the composite fibers;
creating a steel pathway for highly pressurized gas to a pressure vessel by drilling a gas port through the gas key to the center of the barrel;
wherein the gas key will then act as a solid platform to mount a pressure vessel to operate the device.
