Good luck finding a barrel, they are few and far between and expensive when found. I traded into a Road Blocker barrel, cost me about $200 of Russian surplus 5.45x39 ammo I had laying around. That was about 2008 or 2009. It is probably cheaper to buy another Mag-10 and cut down the barrel if necessary. That has the added benefit of having spare parts available as a few are becoming difficult to find.
