I can't get an answer on this one from the manufacturer. Can barrels be interchanged on the ultra rifle. I could order a replacment and see or risk me and my friends rifle and life and limb but I don't want to. I have a .308. It's about as neet as it comes. Buddys got a 25.06. A real tack driver. Can anyone help since N.E. can't even decide who makes the thing.
