I run both of the alg defense triggers, my favorite of the two is the act.

It is pretty smooth with a 4.6lbs pull off my Lyman trigger pull gauge and worth the $69.00.
Reset is not super short and does not give me the "OH Crap that light" uneasy feeling. I use this trigger in my 308 AR.
I have the QMS in my 300blk build and it is very serviceable. It is not as smooth as the ACT, but better then a stock colt 6920 trigger/milspec. My QMS on the Lyman trigger guage is 5.8lbs.
That's my data, you can flush it down the swirly bowl if it's not needed.
