    The Franklin armory BFS 3 is a very nice binary trigger probably one of the best on the market. It works and everything from AR-15 to AR-10 platforms and even PCC AR-15s. The only issue I have seen with this trigger is the lock up between the safety and the selector on the trigger itself could have a little tighter tolerance but if it did it might not be as universal. All in all it's worth the money especially when purchase from recoil gun works
