I have a Montana Rifle Man Barrel for sale. It is a 30 cal 1-10 twist barrel, 26 inches long, and in Stainless Steel. It has been contoured in a # 4 contour which is a mid weight hunter style contour. The barrel was drilled and reamed. Then hand lapped to smooth out the bore. It was then button rifled and once again hand lapped finish the barrel. This has a clean bore and is in great shape. $200 to you door. Save a bunch on this barrel! The shank is at 1.2 in diameter and the crown is at .665.
