i saw that midsouth has 54 cal scout barrels for sale.......will the 54 cal barrel interchange with a 50 cal. rifle??????????THANKS

I had a .50 Scout some time ago and the understanding at that time was that the barrels will interchange on the action which is the same. Maybe someone that has one with both barrels can give you positive information.

Well I own one of each. I was not ambitious enough to take them apart and see if they will swap for you but I did mic the barrels and they are identical O D so I would say go for it.
