MG2 Evo trigger adjustment.

[Ricardo]

Hi all. I have a set of Matchguns MG2 Evo and MG 4. These guns are appropriately called "MG," because they're like a finicky British roadster -lovely when they work, but fiddling with them is part of the bargain. I'm currently finding it impossible to set the second stage on my MG 2Evo for any weight between 850 g or so and 1,350 or so. My MG4 is set at a lovely 1,100 g and I'd like to get a similar setting here. However, any tiny movement of the inner screw for "release pressure" or "release force" (whatever it's called) jumps right over the values I mentioned. First stage is at 400 g, no problem there, and I increased overtravel in case I had it too tight. I wonder if I need to do something else first.

This You Tube video helped me out on the MG2evo trigger.

Oh, that looks very promising; thanks! I had seen one other of his videos, but didn't know this one.

One issue I ran into is that the they used too much threadlocking compound on the inner (2nd stage force) screw on one of my MG2's. It was pretty much frozen in place. Every time I tried to move it, the hex key would slip and I was sure I had stripped the hex out. Once I got the outer screw out (which requires removing at least the trigger & possibly the primary release lever), what I found was that the inner hex was 3/4 full of thread locker. Once I chipped that out with a needle, I could get a hex key in far enough to turn the screw OK.

If you are trying to adjust the starting position of the second stage, the thread on the outer screw is moderately coarse, and it can be pretty touchy. It helps to put some sort of mark on the outer screw so you can see how much it moves. I use a fine tip silver paint marker to put a spot on the front end of the screw. The mark is also helpful to make sure the outer screw doesn't shift when you are adjusting the inner one.

Great advice; thanks!
