Works great in saint victor 5.56 - OpticsPlanet Exclusive Franklin Armory BFSIII AR-C1 Trigger - Binary Firing System for AR Platforms

Installed into an otherwise stock Springfield Saint Victor AR15 with a 16 inch barrel chambered in 5.56. Install was easy enough, just follow a guide on YouTube. I didn’t need to change my buffer spring out for either of the ones included, but it’s really nice they include 2 with different spring weight just in case. Took her out to the range, and she spit bullets like a dream. Shot a Full 30 round PMAG with green tips in Binary mode flawlessly. Will definitely be buying more of these triggers for future builds.
