They appear to be the correct bayonets. Whether they were switched from piles of surplus, I don't know. The notch on the barrel band that the bayonet handle notch locks into lets the bayonet hand down a quarter inch from being snug to the stock. I had one unissued, that I sold, where every thing was fine. It appears the notch on the barrel band or the bannot notch was filed down a bit or wore that amount. I don't have equipment to weld a bit and grind it down. Surely there is a simplier answer that escapes me.
