I have a barrel off of a renegade I bought for a project. It is a .50 cal barrel. Barrel does not have any sights (as shown). It shows some exterior wear on the edges of the flats as shown. The rifle had a scope mounted on it previously. From what I can tell the barrel is in good shape. I ran a few patches down it and it was almost spotless. Barrel measures 27" to the base of the breech plug (26" barrel).
I also have a renegade mount if you are interested. The mount is a TC base adapter and screws onto the tang and extends forward. I would have to double check the exact model number.
$80 shipped OBO for the barrel
