Winchester M1873 Randall GAS
The air-cocking Randall has been converted to a gas gun. The external appearance is identical to the air-cocking model. Gas conversion has made the lever operation significantly smoother than before.
The Winchester M1873 is a famous firearm, also known as "the gun that conquered the West," alongside the Colt Peacemaker (SAA).
This is a special specification featuring a rare octagon barrel, which has been boldly shortened along with the stock, and a significantly enlarged loop lever.
It's a very easy-to-handle model that can be operated and fired with one hand.
The SAA and Winchester rifle are models that almost always appear in Western movies.
The exterior is also reproduced with high quality; although the stock is plastic, it has a painted finish resembling real American walnut.
