Hello friends. On Thursday I got a 556 Swat from my local gun store I've been going to for years because I've always wanted one and never pulled the trigger. I'm at the phase in my life where I'm just buying all the stuff I wish I bought back when they were half the price.
Anyways, I'm a bored Engineer and in my free time I've been making silly parts for Daewoo rifles for the past handful of months and now that I have this gun I got bored and started designing parts for it that I wanted.
Here's the regulator modeled basically as it is from the factory, but with 2 smaller positions on the opposite end for suppressed use.
The Daewoo regulator design required more thinking and work to turn a 4-position system into a 6-position but the Sig system really looks like it would be pretty easy to just add a third detent indentation in the middle and a new port in between the current ones. The spacing is just far enough to ensure that only one port at a time is seeing gas. Maybe the most work involved would be knocking out a roll pin and increasing the tension of the spring behind the detent, but that's only if adding that third position per "wing" on the regulator makes it a little too easy to go between settings, etc.
Any input on a 6-position version? Good idea? Bad idea?
For reference, here are pictures of the Daewoo regulator, and some other parts I had made. All steel parts machined from 4140 that was then Black Nitrided for hardness.
And some 17-4 stainless charging handles with HP MJF Nylon knobs
So yeah, I'm gonna prototype some parts for myself that I want, but I'm curious what everyone else wants. Personally even though I have big hands the safety kind of sucks to use, so I might throw something together akin to the extended levers for the MP5 for fun.
