The gas port so close to the muzzle I think is what makes the M1 such an accurate semi auto so I wouldn't change that. I would modify the oprod to have a seperate piston and a more in-line stroke.....a long piston, then shorten the oprod to compensate for the difference. Just to reduce some of the stresses put on the long curvy 3 piece welded oprod
And an adjustable gas nut similar to the shuster set up......but just for civillian use
