Reliable but heavy pull weight. - Fostech Echo Sport AR-15 Binary Trigger

First off they are right about the install not being the easiest, it took me around 20 min to install. The model I received has a slave pin that you push out with your trigger pins. The trigger pull is over 10 lbs and my gauge won’t measure it. The semi auto reset is on par with mil-spec. However the binary mode hammer release from the pinned trigger is really short and crisp that the recoil almost assists it. I can easily control short 4 rd burst but beyond that the trigger weight holds me back with accuracy.
