Steve's Review of OpticsPlanet Exclusive Franklin Armory BFSIII AR-C1 Trigger - Binary Firing System for AR Platforms

I bought 2 of these triggers, 1 I installed in a factory built lower for 300 Blackout and it installed in about 10 minutes and functioned flawlessly in test mode. the 2nd I installed in an 80% billet aluminum lower I machined for a 5.56 upper and I had to tear down and mill the trigger pocket floor deeper than I normally would even for a 1 pc trigger assembly. It took about an hour to finally get it to function properly. Next week i will test both in live fire situations.
