Nice and heavy duty - Weaver Thumbnut SPR 30mm Mount

I own 3 now and keep coming back. I know the are a little heavy but made like a tank. I put these on my long distance build so weight is no bother to a big guy like me. Solid and heavy duty. No worry about the mount being the problem or excuse for missing . I might give the next weaver higher up a try since it is made in the USA unlike this one made in China.
