Franklin Armory BFSIII ARS1 Trigger for AR Platforms 5.56 223 Compatibility

The Franklin Armory BFSIII AR-S1 Binary Firing System III Trigger for AR platforms delivers a three-position operation with Safe, Semi, and Binary modes, offering a fast, single-tension path that makes it the quickest semi-automatic trigger on the market thanks to a binary firing cycle that releases one round on pull and one on release. In position 3, it fires one round on pull and one on release, while position 1 remains Safe and position 2 operates in Semi, delivering 1 round per pull; the release round can be canceled by simply moving the patent-pending selector out of Binary mode while holding the trigger back. This trigger features a smooth 4.5 lb pull with a positive reset, enhanced buffer springs for optimal flexibility, and easy installation, working across most AR platforms and calibers including 5.56 NATO, 308 Win, 300 BLK, 9mm, and even rimfire, with compatibility to any bolt carrier group. It is ideal for competition, tactical applications, and recreational enthusiasts seeking tighter groups through greatly reduced split times between shots. The package includes two ATI Schmeisser S60 magazines in a Gen 2 Military/LEO edition, and while using the BFSIII, professional installation and proper training are essential for safe operation.
