Great binary trigger - OpticsPlanet Exclusive Franklin Armory BFSIII AR-C1 Trigger - Binary Firing System for AR Platforms

Love the design easy to install comes with everything you need..only hitch is you may have to play with your buffer weight and spring to make it run reliable...price range is okay..it was delivered fast...i had a few hickups at the beginning but after adjusting to a heavier h3 buffer and 42 g spring worked flawless..i def recommend if you like to go fast like ricky bobby
