In all seriousness, I've never changed out a trigger in anything. It's always been a matter of learning that weapons quirks and flaws. The only trigger I've even installed was in the lower for my AR, and that was donated to my build by a friend as he upgraded to a Timmony trigger. I see the price tags on some of these triggers, and can't see how it could be worth the money.
This might sound like sacrilege, but to me, a trigger is just a trigger.

the only real difference between a good tracker and a bad tracker, is observation. all the same data is present for both. The rest, is understanding what you're seeing.
