These 1/200 Scale Mk12 38cal 5" guns are meant to be a direct replacement for the kit supplied USS Fletcher guns by Trumpeter. They will also fit the USS Stevens and Sullivans kit.
Our 3D printed guns are the correct size for the 1/200 scale ships. The kit supplied parts are too big. You will receive 2 "double knuckle" and 3 "single knuckle" guns. We have referenced several resources to come up with an accurate design that will accommodate most versions of the Fletcher Class Destroyers.
