Franklin Armory BFSIII AR-Essential Binary Rifle Trigger Features The Franklin Armory BFSIII AR-Essential Binary Rifle Trigger operates in three distinct positions to deliver adaptable performance. In Safe mode the firearm will not fire in Semi mode it fires one round per pull and in Binary mode it fires one round on pull and one round on release. This AR binary trigger system significantly reduces split times between shots helping shooters maintain tighter groups and improved follow-up speed. The patented selector allows the release round to be canceled by moving the selector out of Binary mode while holding the trigger to the rear. A single-sided selector shaft resembles a standard mil-spec AR selector making it ideal for traditional or retro-style builds. Compatible with most AR platforms and calibers including 5.56 NATO .308 Win .300 Blackout 9mm and rimfire variants it works with most bolt carrier groups and is designed for straightforward installation with a positive reset on release.
