Re: diy carbon barrel sleeve?
I have done several 10/22 barrels. I turn the front sight boss down to 7/16 and thread to 7/16 NF. Turn barrel from 1" from breech to 7/16" with big radius. Turn breech end of barrel 1/8" down from original dia. leaving a shoulder out 3/4" from breech. Machine aluminum tube to fit over barrel from alum. conduit. Fab SS nut to screw on barrel to tension. Mill 2 flats on muzzle sides to hold barrel while tightening nut. Will shoot as good or better that Vol. barrel.
