I was among the first people in the United States to put hands on a commercial TAVOR at Bullpup Shoot 2012. Like most bullpup designs, it has a trigger with room for improvement. It sounds like Geissele Automatics, who knows a thing or two about improving triggers, may be coming to the rescue. They are currently developing a TAVOR Trigger that will be similar to their excellent SSA trigger. It will be a two-stage design with 2.5 lb first stage and a 2 lb second stage.
