The barrel is the same size as the Tamiya kit barrel and fits into the mantlet the same as the kit barrel without any problems although the fit is a little loose with a bit of movement that you will have to deal with but other than that it's a straight fit.
The Tamiya kit barrel has the separate end cap that requires the join seam to be filled and the metal barrel eliminates that minor problem completely with the only quibble being it lacks the subtle flare at the end of the early 75mm M3 barrel.
A simple but effective update for the Tamiya kit that adds a nice detail touch.
Thanks to my credit card and Hobby Easy for the review set.
