Many friends think that the bayonet on the rifle is not accurate, which comes from a plot in the American drama Brother Company. The veteran told the recruits that the bayonet on the M 1 was not hit correctly. This is actually a special case of M 1, because the scope and bayonet seat of M 1 are on the same fixed structure, but this structure is unstable, and the bayonet will encounter a quasi-constellation after being installed.
