Brownells 75th Anniversary - A Shooting Heritage

A Unique Binary Trigger System Designed for the AK-47

For those looking to get a bit more performance out of their AK-style rifle, Franklin Armory has just the upgrade needed, thanks to the company's unique Binary Firing System. Available initially for AR-style rifles only, the company adapted its BFSIII Trigger to the popular AK-47 platform, allowing users to get two shots in the same trigger motion that traditionally fires a single shot in standard semi-automatic actions.

The way the Franklin Armory BFSIII Trigger works is through a third selector-switch position. The first position, like on all drop-in trigger units, is "Safe." The second position allows for true semi-automatic fire, with one shot fired for every pull-and-release motion, like any standard semi-auto trigger. However, the third selector position is where rifle owners can get two shots from the same motion that traditionally fires a single shot in any semi-automatic platform, firing on both the pull and the release of a trigger.

Each Franklin Armory BFSIII Trigger is fitted with an ambidextrous safety selector, and the trigger may need additional fitting on some rifle receivers. The trigger will not work on guns fitted with an underfolding stock, and it will also not work on AK-style 12-gauge shotguns. The system also features a built-in safety, which allows users to cancel a release shot by simply holding the trigger to the rear while moving the selector switch to "Safe."
