The BFSIII Binary Firing System is a three-position trigger for AR platforms, which is ideal for recreational, tactical and competition use. It features a three position selector that allows the user to switch from Mode 1 for safe, Mode 2 for traditional semiautomatic or Mode 3 for binary mode. In the binary mode position, it will fire one round on pull and one round on release, making it one of the fastest semi-automatic triggers on the market. The BFSIII provides greatly reduced split times between rounds and the ability to place two separate shots into a tighter group. It works for most AR platforms including AR10 (308 WIN), AR15 and pistol caliber carbines. It also works on both 9mm and .22LR uppers without modification.

What a Great Product

This was my first Binary Trigger. I checked out both Franklin Armory and Fostech triggers with Franklin being the winner. Now to find one at the best price and delivery. I found that most vendors were out of stock except for BudK!!!!! The price was one of the lowest with fast shipping. This trigger was installed in 20 minutes (after removal of the standard AR-15 trigger) with all the "checks" required to assure it was operating properly. What fun this trigger is to shoot. Others at the range that day enjoyed hearing the rifle work well.

What a Great Product

OMG!! I Love This Trigger

This is actually my fourth trigger to buy. The Franklin Armory trigger is great. I have installed a Fostech that was complicated. I also have one in my scorpion and I love it. my wife has tried the trigger several times even my grandson. It is great!!! It was easy to install and the instructions were awesome.

OMG!! I Love This Trigger
