Barrel nut Attaching the barrel to the receiver using a barrel nut and a barrel with a shoulder is an alternative to action threads, which has been used in firearms such as the Sten gun and AR-15. Hand tools Quick barrel change systems is an increasingly popular alternative, as seen in for example SIG Sauer 200 STR, Roessler Titan or Blaser R8.
A muzzle brake works by diverting gases perpendicularly relative to the barrel to reduce felt recoil. The greater the gas volume, or the pressure that gas is at, the more force the compensator or muzzle brake creates. Competitors could "feed" a compensator more gases than comparable .38 Super loads. However, the muzzle blast also increased ...
An 18-inch (457 mm) (MOD 0/1) or 16-inch (406 mm) (MOD H) threaded-muzzle match-grade free floating stainless steel heavy barrel with a 1:7 (178 mm) rifling twist ratio is standard for the SPR. [11] [3] [13] The barrels are manufactured by Douglas Barrels with a unique contour that reduced weight but maintained rigidity for accuracy. [14]
It features a rotary bolt with six locking lugs, arranged into three pairs at the bolt head, a polymer stock with aluminium alloy chassis, and a solid, flat-bottomed receiver made of steel, the AI (Accuracy International) muzzle brake (optional), a detachable suppressor, a 20-, 24- inch plain or threaded barrel, and a 26-inch threaded barrel ...
A female worker boring out the barrel of a Lee-Enfield rifle during WWI. Gun barrels are usually made of some type of metal or metal alloy.However, during the late Tang dynasty, Chinese inventors discovered gunpowder, and used bamboo, which has a strong, naturally tubular stalk and is cheaper to obtain and process, as the first barrels in gunpowder projectile weapons such as fire lances.

It used threaded pipes for simplicity. In some cases, guerrillas have used improvised, repurposed firearms. One example is described by Che Guevara in his book Guerrilla Warfare. Called the "M-16", it consists of a 16 gauge sawed-off shotgun provided with a bipod to hold the barrel at a 45
The receiver is made from two parts (upper and lower), stamped from sheet steel and connected by cross-pins. The heavy barrel is fluted to improve heat dissipation and save weight, and fitted with a large and effective reactive muzzle brake. The muzzle brakes on the earlier models had a round cross-section; later M82 rifles are equipped with ...
Walther P99 with the slide locked back displaying its vertical barrel tilt. The Walther P99 is a short recoil-operated locked breech semi-automatic pistol that uses a modified Browning cam-lock system adapted from the Hi-Power pistol. The P99 has a glassfiber-reinforced polymer frame and steel slide assembly.
