It depends on the size of the barrel ring, that particular design bayonet has three rifle design possibilities that I know of 1. M1 Carbine, 2. AR15/M16, or 3. M14/M1A, you'll have to actually fit it to find out for sure as I said the size of the barrel ring and a possibility of some internal design difference in the lug fitting will make the difference as to the actual weapon it fits properly.
