Making A Fire Control Module

The fire control module for the SIG 320 is deceptively simple.

I suspect that lots of people are going to learn that forming sheet metal isn't as easy as they think it is.

I learned a lot about it designing vending machines and their attendant little parts.

Tolerance stacking is not your friend and there are many forms that you can't make by simple bending.

If you want to give it a shot with a simpler exercise: Make a magazine.

It's just a rectangular tube, easy peasy!

What will be real fun is for someone to make a modular fire control unit that can be made from sheet stock from Home Depot and that little finger brake that Harbor Freight sells.

The Ghost Gun people gonna have a heart attack!
