Very nice binary - OpticsPlanet Exclusive Franklin Armory BFSIII AR-C1 Trigger - Binary Firing System for AR Platforms

I purchased one BFS to try on multiple platforms. The .300 Blackout did not cycle with the BFS. The two .223/5.56 platforms functioned perfectly. One of my 5.56 platforms has the Gemtech suppressed bolt carrier and AAC suppressor. The BFS functioned perfectly in this rifle. I will be closetting my bump stock and getting two more of the BFSs. Everyone at the range with me agrees this is the way to go. Great design and easy to install. Also, the selector switch has a large gap with the lower frame. Almost as if the selector shaft could be reduced in length by 1/32nd inch. There are two identical springs. I was told they are different stiffnesses. Have to try them both to determine which works better.
