Custom Trigger Project
« on: April 18, 2015, 07:21:46 AM »
Has anyone yet to try and machine their own trigger at home? I was going to attempt today using some left over A2 steel I had, and a print from RifleConnection Blueprints , I have double checked the dimensions on a cheap milspec I already have and all seems dead on. Also what type of heat treating should I do? Do I need to really case harden the hammer? Its a great set of prints that contains the hammer, trigger, and catch, but just starting with the trigger since I want to modify it into a flat trigger without curve.

Hardening the hammer, sear and trigger is important. If the steel is too soft, the sear will wear leading to trouble down the road, including doubling, tripling and even uncontrolled full auto

I don't know what print or drawing you have but I know the 1911 prints have sear and hammer hardness call out of 43.5 -50 HRC. Why the .5 I don't know and if there is any correlation to the ar platform I'm not sure either. Just throwing it out there to consider.

The heat treatment and metallurgy requirements are spelled out on the original M16 prints.
