That’s an idea butlersrangers, there supposedly was a Springfield Bushmaster carbine with an 18 inch bbl but it wouldn’t take a bayonet. If nothing else when I’m done I’ll have a nice 1903 ‘school’ gun. I am thinking about getting a repro 03 bayonet and opening the muzzle ring to fit the shorter bbls slightly larger diameter. My milsurp rifle theory appears to be ‘if it’s got a bayonet mount it’s gotta have a bayonet.’
