I have a Franklin Armory BFSIII AR-C1 binary trigger up for sale or trade. It operates with a standard AR safety selector with safe, fire (semi auto), and the added benefit of the “happy switch” position for binary mode. Right now it’s on sale for $387 plus tax and shipping from their website, so I’d ask $400 cash or trade value and you save a few bucks. I had this installed in a rifle and it works flawlessly but for me it was somewhat of an impulse purchase. It does come with all the original packaging. I’d be open to many trades for firearms (with cash on my end if needed), factory ammo, or silver. I live in DeMotte (NWI) but occasionally go either east or towards Indy.
