I installed a rifle basix sav-2 trigger in my build. Pretty much dissatisfied because of random disengagement of the sear (firing). I followed the instructions carefully, but it seems that the sear engagement is so slight that any banging, jarring or closing of the bolt hard will cause the gun to fire. Even when adjusted to over 2 pounds pull, it is fairly easy to get it to go off without pulling the trigger. Any better trigger options out there?
