T/C Thompson Center Scout Barrel 54 Caliber. Very nice condition with bright shiny bore. The breech plug area that fit inside the trigger assemble measures. My guess is T/C made this the same size for the different calibers but I don’t have anything to compare and measure so please measure your current barrel breech area. The barrel itself measures. 970 in diameter to confirm if your forend and barrel band will fit this. The total length is just under 24 This includes the breech area.
