I have a 16" sporter weight ER Shaw 300 blackout barrel. I bought it a few months ago but have lost interest. It's stainless, 5/8x24 threaded at the muzzle and prefit for a savage small shank. Picture is not of my barrel but is the same. $240 shipped Also have a 26" Douglas varmint contour 22-250ai barrel. 1-8 twist. Shoots 75gr amaxes great. Stainless, currently painted green but will come off easy enough. I have the go gauge for it too. Has about 200 round thru it. $220 shipped Would trade toward 7mm RM, 300wm or a .223 heavy barrel.
