Description
The Franklin Armory BFSIII 22-C1 is a Gen 3 Binary Firing System built specifically for 10/22 style firearms, and it flat out changes how much fun you can have with a rimfire. This is a three-position trigger with an ambidextrous safety selector: position one is Safe, position two runs standard semi-auto, and position three is Binary, where the rifle fires one round on the pull and a second round on the release. That means two rounds for every full cycle of the trigger, which is what gives it those crazy fast split times and puts it in the running as one of the quickest semi-auto triggers you can bolt into a 10/22.
What the 22-C1 Feels Like Behind the Trigger
Beyond the party trick, this is just a good trigger. It breaks crisp in the 4-pound range with a positive reset and not a lot of overtravel, so even in plain semi mode you're getting an upgrade over the mushy stock 10/22 unit. If you don't want that release shot on a given press, just flip the selector out of Binary while holding the trigger back and the release round gets cancelled. It's a genuinely handy feature that keeps you in control instead of the trigger controlling you.
Installing the BFSIII 22-C1 in Your 10/22
The 22-C1 drops into a vacant Ruger 10/22 trigger housing and assembles a lot like the factory trigger pack, so anyone who's tinkered with a 10/22 before will recognize the layout. It ships as a factory-configured assembly with the parts neatly organized, and only a few basic tools are needed. That said, this is a precision fire control component, so a gunsmith install is recommended, and some folks find a short break-in period smooths everything out.
With steel internals, a black finish, and a curved trigger shoe for comfortable finger placement, the BFSIII 22-C1 is built to hold up to a whole lot of range time. On a 10/22 with cheap .22 LR flowing, the grin-per-dollar factor is about as high as it gets.

Frequently Asked Questions
How does the BFSIII 22-C1 binary trigger actually work?
It's a three-position trigger. In the first position it won't fire, the second position is standard semi-auto, and the third position is Binary, which fires one round when you pull the trigger and a second round when you release it. That gives you two shots per full trigger cycle and dramatically reduced split times.
Will the 22-C1 fit my Ruger 10/22?
The 22-C1 is designed for Ruger 10/22 and 10/22 style firearms, and it drops into a vacant Ruger 10/22 trigger housing. It assembles very similarly to the factory 10/22 trigger pack, so if you've worked on one before it'll feel familiar. Franklin Armory recommends gunsmith installation to make sure everything functions correctly.
Can I cancel the second shot if I don't want it to fire on release?
Yes. If you're holding the trigger back in Binary mode and decide you don't want the release round, just move the selector out of Binary while the trigger is still pressed and the second shot is cancelled. It's a nice safety-minded feature that keeps you in control of each shot.
Is the BFSIII 22-C1 a good trigger even in normal semi-auto mode?
It is. The 22-C1 has a crisp break in the roughly 4-pound range with a positive reset and minimal overtravel, so it's a real upgrade over the stock 10/22 trigger even before you touch Binary mode. Some owners find a short break-in period helps everything settle in and run its smoothest.
