i have a .920 bull bbl for my 10/22 that is 20" long and fluted and wanted to know if you could cut it down and thread it so that the bbl. shoulder is about 1/4" from the flutes. i will be mounting a supressor to this bbl. as well just to let you know. also, could you make a thread protector that is knurled and close to the dia. of the bbl.?
here's a pic of the bbl. needing work.
