Works great on 10.3” barrel - Fostech Echo Sport AR-15 Binary Trigger

chris's Review of Fostech Echo Sport AR-15 Binary Trigger
I don’t see why so many people are having trouble, maybe I got lucky and didn’t get a defected one? I got mine at a gun show and it was so good my cousin went back the next day to drop two hundred on it, yes it was hard to install but ran very smoothly in both semi and echo mode once properly seated.
