Franklin Armory AR-Essential Binary Trigger AR Platform Curved

The Franklin Armory AR-Essential is the BFSIII binary trigger with just the parts needed to put binary fire into an AR lower. It has a curved trigger blade and a single sided three position selector that looks like a standard mil-spec AR selector, a good fit for a retro build.

Position 1 is safe, position 2 fires one round per pull, and position 3 (binary) fires one round on the pull and one on the release. Moving the selector out of binary while holding the trigger back cancels the release round. Franklin says it works in most AR platforms and calibers, including 5.56 NATO, 308 Win and 300 BLK, and with most bolt carrier groups. It is not for 80% lowers, polymer lowers or carbon lowers, and the trigger pin size is .154". Binary triggers are not legal for civilian sale in every state, so check your state and local law first.
