Franklin Armory BFSIII AR-S1 Binary Trigger System

Franklin Armory BFSIII AR-S1 Binary Trigger System III — Straight trigger package. This is a three-position binary firing system for AR-style platforms that fires one round on the pull and one round on the release when set to the binary position.

The primary purpose of the BFSIII is to allow a semi-automatic firearm to operate in a three-position mode that provides a round on pull and a round on release in the binary position. That behavior shortens the time between consecutive shots compared with a standard single-action semi-automatic trigger. The unit is intended for use in AR-platform rifles across a range of calibers and for applications such as competition and range use where that firing mode is desired.
