Franklin Armory BFSIII AR-S1 - DB9R 9mm AR Pistol
UPDATE: I have abandoned the Franklin Armory triggers completely due to the ease with which you can outrun the trigger and end up with a dead trigger. I don't enjoy having to eject a live round out of the gun every few shots. It is frustrating and the FosTecH Echo does not have this problem. I know Franklin is making triggers for more platforms, but I will avoid them like the plague until and unless I personally shoot one that does not have the same problems as the BFS gens I, II, and III.
Just received my Franklin Armory Binary Firing System III AR-S1 triggers today. Installed one in this Diamondback DB9R 9mm AR pistol and took it out to see if it was an improvement over the first gen BFS triggers. I managed to outrun the trigger quite frequently, so I'm going to have to practice more and reserve judgement for later; however, my initial opinion is that it does function MUCH better than the first gen, but it is still quite easy to outrun and end up with a dead trigger.
