Our UL-NW-4 is a bit longer, to fill old dovetails, or to slot for your key. Milled steel, the flat base is .465" wide, by .750" long, with a large surface for a good solder joint, if desired. The base is .050" thick, ideal for thin wall barrels. The blade is 0.075" thick and stands 0.19" above the base. Most rifles will use three underlugs, while barrels longer than 42" use four. Made in the U.S.A.
