New Made Item: Originally designed for the Winchester M-1897 Riot Shotgun, these ventilated barrel jackets with mounts for the M-1917 Bayonets, were introduced in WWI for trench warfare and used continually up through the war in Vietnam.
This is a quality steel reproduction that can be retro-fitted to your pump action M-1897 or similar weapon and bring it to "Trench Gun" specifications. Another scarce WWI accessory that is now available as a reproduction.
