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.
This is a problem in many manufacturing processes, especially the firearms industry: the barrel of a gun must be very straight and accurately sized. Gun barrels are far longer than their inside diameter; as an example, the .223 inches (5.7 mm) caliber barrel of the M16 rifle is 20 inches (510 mm) long, nearly 90 times the diameter of the bore.
Interrupted screws are occasionally seen in loose gunpowder rifles, as this mechanism was historically one of the few practical ways to achieve a gas-proof seal with a breech-loading firearm that does not employ metallic cartridges. An earlier method was the use of a wedge to block the rear of the gun.
A patented AR-15-pattern is produced with a bolt design featuring a redesigned extractor intended to improve the extraction of cartridges under adverse conditions. The company also produces a redesigned bolt carrier intended to improve the reliable performance of the rifle's “internal piston” system by obtaining a similar timing sequence with 14.5-inch carbine-length barrels compared to 20 ...

Conversions for rifles and carbines of larger caliber, such as the AK-47 or Thompson submachine gun include a rifled insert barrel extending beyond the length of the chamber. [9] [10] One exception to the use of a special lightweight bolt was the Colt Service Ace, offered as a complete pistol or as a conversion kit for the M1911.
A part's-eye view of a boring bar. Hole types: Blind hole (left), through hole (middle), interrupted hole (right). In machining, boring is the process of enlarging a hole that has already been drilled (or cast) by means of a single-point cutting tool (or of a boring head containing several such tools), such as in boring a gun barrel or an engine cylinder.
A gun barrel is a crucial part of gun-type weapons such as small firearms, artillery pieces, and air guns. It is the straight shooting tube, usually made of rigid high-strength metal , through which a contained rapid expansion of high-pressure gas(es) is used to propel a projectile out of the front end ( muzzle ) at a high velocity.
