Large Frame Lever Action Rifle Barrels 4140 Steel

Green Mountain offers large frame lever action rifle barrels for the .50 express cartridge as used in the 1886 Winchesters. These rifle barrels feature 4140 Chrome-Moly steel. Other rifle barrel companies harden their steel by adding carbon and then heating it. This process often warps and distorts the barrel.

On the other hand, Green Mountain's large frame lever action rifle barrels are alloyed with Chromium. Chromium helps to reduce corrosion. Over time, Chromium alloy has become the gold standard in barrel making. It combines the strength of a medium carbon steel with the abrasion resistance provided by the molybdenum alloy.

Green Mountain barrels use this chromium alloy to increase the strength of your rifle barrel without warping and distorting it. A stronger rifle barrel resists abrasion, which means your rifle barrel will shoot accurately for longer than other rifle barrels.

These rifle barrels come octagonal and round. All are tapered, with twist rates from 1:54 to 1:14. Choose yours cut rifled or button rifled.
