Great trigger so far - Triggertech AR-15 Adaptable Trigger

Little more work to install it than a regular drop in trigger, but smooth, crisp trigger pull. Says it goes down to 2.5# but with a trigger pull scale, i got mine down to 2.3-2.4# for my 6.5 build. Down side is that they include 2 allen wrenches, but theyre the same size. Make sure you have your own 1/16th wrench to tighten the 'set' screws that secure the position of the trigger
