A gun barrel or sleeve for a gun barrel is provided. The invention includes staggered helical arrays of elliptical or oval blind cavities along the length of the gun barrel or sleeve. As a sleeve, the invention may be press-fit or force-fitted over a regular barrel or a barrel of reduced wall thickness. The cavities have radially extending orifices by which an angular width of an interior portion of a cavity is greater than an angular width of the orifice of that cavity, and a longitudinal dimension of the interior portion of that cavity is greater than a longitudinal dimension of the orifice of that cavity. The product may be produced by additive manufacturing, autofrettage, casting, forging or traditional CNC machining.

A method for forming and a carbon fiber barrel sleeve resiliently bonded to steel liner includes providing a rifle barrel having thickened walls and a mandrel blank. Each of the barrel and blank are turned to form a barrel liner and a mandrel, respectively, such that each has a substantially identical contour. The barrel liner is stress relieved to eliminate stresses within the molecular structure of the barrel liner. A plurality of flutes are cut into an exterior surface of the barrel liner; the depth of each flute being at least equal to the depth of the flute. A plurality of layers of carbon fiber fabric are laid up on the mandrel to form a sheath which is cured and bonded to the barrel liner with a continuous bond of high temperature adhesive at tips of the fins. The bonded sheath and barrel liner forming a rifle barrel.

Disclosed herein are composite shafts for sporting goods, such as archery arrows, golf clubs, and rifles, which include a reinforcing layer to improve the performance of the sporting goods.

Disclosed herein is a test gun barrel for use with a long range projectile testing system. The test gun barrel comprising a main gun barrel and a gun barrel extension. The main gun barrel and gun barrel extension each include a joint end having aligning cylinders and bores to properly align the main gun barrel to the extension prior to engaging threaded coupling. A seal capable of being inspected is made once main gun barrel is fully coupled to gun barrel extension.

In one aspect, a sensor system for advanced smart weapons barrels includes one or more sensors, the sensors connected to a processor by way of conductive elements. The smart weapons barrel system may include one or more barrel segments, such segments being removably attached to each other. In certain embodiments, the sensors are positioned along the barrel segments and generate an electrical signal in response to a projectile being fired by the host firearm as the projectile moves past the respective sensor. The processor receives raw data from the sensor signal and may extrapolate and/or calculate further information in order to determine any number of a variety of metrics or other data analysis, including, but not limited to, round count projectile velocity, rate of fire, etc.
