You can easily mount a scope; the receiver is drilled and tapped from the factory but I can't see a scope as very practical on such a gun. I bought one of these guns new thirty years ago. Mine is in .45 Colt. I've yet to figure out what it's good for, but it shoots cast bullets so accurately, I can't part with it. Sighted in at 50 yards, the 255 grain bullet drops about 5" at 100 yards, probably not much flatter shooting than a handgun in the same chambering. A .30-30 should have a slightly better trajectory.
