The barrel may be able to be fitted however the shotgun would still be limited to 2-3/4" shells. A longer stroke of the bolt is required when shooting the 3" magnum shells which requires a different receiver.
Not the best idea.
It will fit on the frame but the action will not function with 3 inch shells.
During the time frame of 1966 to 1971 Browning salt cured (or salt dried if you prefer) their stocks. When rust problems began to arise, Browning offered to replace the "salt wood". You had to prove you were the original ower as the warranty didn't transfer to subsequent owners.
Needs to be sent to a Browning authorized repair center.
