Fantastic 2-stage ar trigger! - FM Products Foxtrot Mike Premium Match Grade 2 Stage Competition AR-15 Trigger Group

I bought this trigger for my new AR-9 build after the mil-spec trigger gave me double fires and a scary out-of-battery discharge. Research indicated that the trigger group was probably at fault, and some advice suggested a 2-stage trigger would tend to work better in a blowback PCC. Two-stage trigger operation is surprisingly different from a single-stage trigger (also note difference in hammer shape.) I suspect the "tail" of my mil-spec hammer was sometimes whacking the disconnector due to the ultra-fast bolt recoil, preventing the hammer from locking in.

Installation was easy - not really much different than any other AR trigger. Trigger and hammer are very well made. Small writing on the trigger body says "1005 Tactical."

I just got back from the range, and my AR-9 ran 150 rounds without a single firing problem!!! Trigger operation is smooth, and the break is light and fairly crisp. Takeup takes very little effort. This is my first experience with a 2-stage trigger, but I liked it very much. I may buy an extra to try in my other ARs. You really cannot beat it for the price. HIGHLY RECOMMENDED.
