Reviews for Fostech Echo AR II Gen 2 Binary Drop In Trigger For AR-15 Proprietary Bolt Carrier Not Req'd

Ordered 5/6/20 recieved 5/11/20 I watched the Fostech echo install video on YT a few times. I was cautious & was able to install it without issue. I took it to the range the next day and the 1st couple of shots I stumbled a bit on echo mode then all hell broke loose and the gun sang like a top fuel dragster! It was fn awesome! Semi fire mode is a nice clean break 2.5-4lbs short reset. Echo fire mode is mushy and a bit weird feeling. Its going to take me some time to get used to it. If you've got the cheddar go for it, its alot of fun.

Best binary trigger going for AR's and the 2nd time I've nabbed one for $339! I have a Franklin BFS newest gen and it works fine but the Fostech's are faster and smoother IMHO,

Installation was challenging due to concerns about slipping and having all the components explode into the air. Read the instructions! Then reread them a few times until you really understand them. I thought the information on the floating hammer lock and spring at the rear were a bit vague, so pay attention. Installation was brief and without any glitches. I am an old "two stage trigger" guy and the pull on this is a bit mushy but likely OK for CQB. Very easy to dump a whole mag.

Install is easy. Takes 30 minutes + or -. Remember, you must have an M-16, auto, bolt carrier for this trigger to function. Function test was spot on. Best price on the market.
