Thank you for the info guys, a couple of things. I did fire the gun this morning, roughly 300 rounds with no problem from the trigger, my main concern is that it might act up during a match, which I will probably reloctite the set screws on the Armory Craft trigger. The trigger probably has about 1000 rounds on it with no problem before and I just added the gray guns guide rod and at the first match with it, I had some stove pipes as I was using the 15lb spring it came with which led me to want to try a 14lb spring.
