I have heard good reviews about the Briley triggers, you have to send them your whole housing so they can fit it for you. I thought about it, but chose instead to go with an OEM aluminum trigger guard, some Wolff trigger group springs for reliability, I didn't change any pull weights. And I lucked up on a Geissele hammer and threw that in. Thats it, I don't plan on doing anything else to it other than shooting it alot to smooth the action out. But if I had to recommend any kit, I'd go with Briley based on the feedback I've heard from people who actually use them.
