Echo sport vs echo arll - Fostech Echo AR-II Drop-In Binary AR-15 Trigger

installed this trigger yesturday took about 2 minnets I highly recomend this trigger over the sport in mt oppinion it is much more reliable I tried several times to get the sport to function correctly but could not get it to work correctly in a BFI lower pluse you don't have to mess with the paddle on the trigger it's all on the safety switch
