Win Mod12 Trench Gun Conversion

[Tom Doniphon]

The sporting barrels are completely different. Thinner and tapered. The riot and trench are almost a straight taper and thick.

Actually, on the Model 12, the sporting and riot barrels taper. The Model 12 trench gun barrels do not taper. That is why when the Military converted some Model 12 riot guns to trench guns they had to use a sleeve on the muzzle end of the barrel to make the bayonet adaptor fit properly.
