The Mark 7 gun was a built-up gun and was constructed of liner, tube, jacket, three hoops, two locking rings, tube and liner locking ring, yoke ring and screw box liner. Some components were autofretted. Typical of United States naval weapons built in the 1940s, the bore was chromium-plated for longer barrel life.
In most cases, it is not practical to fix a barrel whose bore is worn out, poorly or unsuitably rifled, or the wrong bore diameter; the primary exception to that is rimfire barrels, which can be inexpensively bored out and re-lined with a commercial barrel liner. [36] If the barrel is unsuitable and relining is not an option, then an ...
Liners may be either cylindrical or conical. Conical liners are tapered toward the muzzle for ease of removal from the breech end while limiting forward creep during firing. Conical liners may be removed by water cooling the liner after re-heating the barrel, but cylindrical liners must be bored out. [13]
The U.S. Navy had the 16"/50-caliber Mark 2 guns left over from the canceled Lexington-class battlecruisers and South Dakota-class battleships of the early 1920s. However it was already apparent that the Mark 2 was too heavy to arm the North Carolina and new South Dakota (1939) battleship classes which had to adhere to the 35,000 ton standard displacement set by the Second London Naval Treaty.
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 ...
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.

The Remington Model 30 is a US sporting rifle of the inter-war period based on the military P14/M1917 Enfield rifle action, which was manufactured for the British and US governments during World War I. [4] [5] Initial specimens used surplus military parts with some modifications in order to consume the stock of parts, though further modifications were made as production progressed and later ...
