Fostech AK Binary Trigger: Fast Firepower for Your AK Platform
If you’re an AK enthusiast craving faster follow-up shots without converting to full-auto, the Fostech AK binary trigger is the upgrade you’ve been waiting for. Designed to revolutionize the shooting experience, this trigger allows one round to fire on both the pull and the release of the trigger—effectively doubling your rate of fire while remaining within legal limits.
What Is a Binary Trigger?
A binary trigger is a specialized trigger system that fires one round on the pull and another on the release.
