there are 3 sizes... and the difference is far more then 1/4-1/2 inch
might just be a slight difference in where your outter barrel puts the front sight/gas block?
up to you... but myself I would knock the pins for the front sight/block .. install it all as tight as possible and redrill/grind the new notchs in the outter barrel for the sight/block to sit
or you could find a new more MIl-spec outter barrel
