Franklin Armory BFSIII Flat and Curved Binary AR15 Trigger

Fire at a faster rate with the revolutionary Franklin Armory BFSIII Binary AR15 Trigger. Intuitive design gives this trigger the ability to fire once when pulled and once when released, hence the name Binary Trigger. Even if you decided to not used the binary firing option, this trigger is a great improvement in pull weight and smoothness being only 4.5 LB in comparison to a mil-spec trigger at 6-7LB.

This trigger has three safety positions, safe, semi-automatic, and binary. Additionally, the round fired on release on binary mode can be cancelled by moving the selector to semi while holding the trigger back. This trigger is as easy to install as a regular AR15 trigger and compatible with most AR platforms and calibers. Available with a flat titanium nitride trigger or curved trigger.

Completely legal (in most states) and flexible to whatever your intended use is, the Franklin Armory BFSIII Binary Trigger is fast and fun.
