Would I be wrong to say that David Marshall Williams aka Carbine Williams is forgotten in time. It is easy to look at many before him Samuel Colt, John Browning, Benjamin Tyler Henry, Hiram Maxim, Mikhail Kalashnikov, Richard Gatling, John Garand, Gene Stoner, Oliver Winchester, Mauser brothers. We fast forward today and find that the most reliable rifles in semi autos are the piston operated ones. Although Mr. Williams did not design the M1 carbine it is his operating system that is in there and it's the rise of the piston operated weapons that most people desire for semi-autos in modern times. Thoughts?
