It is generally accurate either way. However, point of aim and point of impact usually change @ 100 yds whether it is extended or not. For example, my 1946 Izhevsk M44 will shoot a bit to the left @ 100 yds, but with the bayonet extended, its spot on. Typically, the M44s the Russians produced were zeroed from the factory with the bayonet extended. Looks like you might have to have a range report and let us know what yours does
