This review covers the rare Winchester-Williams Semiauto Antitank Rifle, a scaled-up M1 Carbine action chambered in .50 BMG. Developed for WWII anti-tank use, it was tested by Canada but never adopted. The rifle features a robust gas tappet system, a 10-round magazine, and weighs approximately 25 pounds, showcasing a unique piece of firearms history.
The Winchester Automatic Rifle (WAR) was developed as a lighter alternative to the BAR, featuring a two-lug rotating bolt and David Williams' short-stroke gas tappet system. Despite passing Army tests in 1944 and limited production of around 20 units, the project was canceled at the end of WWII. It offered a 20-round magazine capacity and a highly adjustable rear sight, aiming for improved individual soldier firepower.
