It is also used by machinists, to protect and beautify tools made for their own use. Bluing also helps to maintain the metal finish by resisting superficial scratching, and also helps to reduce glare to the eyes of the shooter when looking down the barrel of the gun. All blued parts still require oiling to prevent rust.
Later rifles had a 36-inch barrel. The stock was made out of walnut wood, and featured a well defined comb and a narrow wrist. The stock contained a brass patch box, and brass furniture was used throughout the rifle. The rifle was 49 inches in length. Later rifles had a longer barrel, which increased their overall length to 52 inches.
While standard rifle barrels taper from breech to muzzle, high precision rifles will often use a barrel with far less taper, called a heavy barrel, sometimes leaving the barrel cylindrical all the way to the muzzle, called a bull barrel. Either technique greatly increases the stiffness of the barrel by enlarging the average diameter, but this ...
Double rifle: A rifle that has two barrels, usually of the same caliber. Like shotguns, they are configured either in over-and-under or side-by-side. Drilling: A firearm with three barrels (from the German word drei for three). Typically it has two shotgun barrels in a side-by-side configuration on the top, with a single rifle barrel underneath.
Rifling of a 105 mm Royal Ordnance L7 tank gun Conventional rifling of a 90 mm M75 cannon (production year 1891, Austria-Hungary) Rifling in a GAU-8 autocannon. Rifling is the term for helical grooves machined into the internal surface of a firearms's barrel for imparting a spin to a projectile to improve its aerodynamic stability and accuracy.
Bedding epoxy in a stock. Rifle bedding is a gunsmithing process of providing a rigid and consistent foundation for a rifle’s operational components, by creating a stable and close-fitting bearing surface between the gun's functional parts (i.e. the receiver housing the barrelled action) and its structural support (i.e. the stock) that do not deform with heat, pressure and moisture, or shift ...
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.

Conventional eight groove rifling on the left, and octagonal polygonal rifling on the right. Polygonal rifling (/ p ə ˈ l ɪ ɡ ə n əl / pə-LIG-ə-nəl) is a type of gun barrel rifling where the traditional sharp-edged "lands and grooves" are replaced by less pronounced "hills and valleys", so the barrel bore has a polygonal (usually hexagonal or octagonal) cross-sectional profile.
