Any interest in jigs to finish 80% lowers

[customcutter]

Depending on what lowers you use.

A friend had that one, it has some pros such as the milling bit depth set point on it. Although he had to trim part of his various lowers to fit into the jig.

We've recently been using Hell Fire Armory jigs. Although my friend is working on making a jig from steel, especially the top plate to hold up longer.

The Modulus Arms link LRRPF52 posted looks pretty slick.

I've been thinking about that as well. Unless it's hardened steel, it's not going to hold up any better than the aluminum top plates do. Well maybe a little, it'll be like cutting butter with a cold knife instead of a hot knife. I was considering making my top plate out of O-1 or A-2, and not tempering it back after heat treating. That way it would be as hard as the mill cutter.
