Was very easy to install. I used a video I found on YouTube to install. Very similar to installing a normal trigger except the slave pin that has to be knocked out while seating the pin. Functions perfectly

Definately will be running these in all of my ar builds! I got it installed by an experienced gun smith but I think I will tackle the install myself on the next one. I highly recommend this trigger if you're looking to go binary.

Works just as you hope. Have already used for several hundred rounds. Once figured out with correct buffer, works like a dream and puts down a mag in seconds. Highly recommend to friends looking at this trigger as an option.

I have at least a half dozen binary drop ins including Franklin BFS lll and 5 Fostech Echos and now a 3MR and 2 Echo sports. I like all of them but Fostech is my favorite to use only in the ar platform. I haven't had any issues with the Fostech triggers that couldn't be resolved by Fostech, like losing a spring on the Fostech ll. Their very good at helping to resolve any issues.

Received the box open with the slave pin missing but I got it all back together and assembled. The trigger itself is amazing nevertheless and I will be buying another one. Great product but terrible shipping I can’t fault fostech for that.
