I have the Timney trigger in my SCAR 16S it feels a lot better than the original trigger. It has a smooth clean break with no creep. The downside is that I've had 6 light primer strikes out of 750 rnds (500 rnds of PMC .223 55gr 3 light primer strikes and 250 rnds of lake city 5.56 3 light primer strikes) since I installed it and never had one before. Not sure if it was due to the rounds or the trigger. Only 1 of the 6 I was able to fire a second time. Other than that it's really fast to rapid fire the trigger reset is unbeliveable short. I am planning to put one in my SCAR 17s.
