Description
The Franklin Armory BFSIII CZ-C1 is the go-to binary upgrade for the CZ Scorpion, and it's one of the only three-position triggers that gives this platform a true doubled rate of fire. In binary mode it puts one round downrange when you pull and another when you release, which is what makes it the quickest semi-auto trigger you can drop into a Scorpion. The curved trigger shoe keeps the feel familiar to the factory setup, and it ships with an ambidextrous safety selector so lefties and righties both get the same clean operation.
What the BFSIII CZ-C1 Actually Does at the Range
The magic here is the three-position selector. Position one is safe and won't fire, position two runs like a normal semi-auto with one round per pull, and position three is the binary setting that fires on pull and release. If you're in binary and decide you don't want that second shot, just flip back to semi and let the trigger out safely. The payoff is dramatically shorter split times and the ability to stack two shots into a tighter group, which is why it's popular with competition and dynamic shooters who want to push their Scorpion's speed.
Fit and Install on the CZ-C1 Trigger
This unit is designed for the CZ Scorpion EVO 3 family, including S1, S2, pistol, and carbine variants. It's a complete drop-in replacement that doesn't need any of your factory internals to work, and it'll even replace an existing aftermarket trigger group like an HBI setup. Most folks who've done the swap report it takes around 15 minutes, and Franklin Armory includes a thorough dry-fire testing procedure to confirm everything functions correctly before you head to the range.
Built in the USA with a steel trigger group and a pull weight in the neighborhood of 4.5 pounds, the BFSIII CZ-C1 is a serious piece of hardware for anyone looking to get the most out of their Scorpion. It's a range-day favorite that turns an already fun platform into something genuinely wild to shoot.

Frequently Asked Questions
Is the BFSIII CZ-C1 a drop-in install on my CZ Scorpion?
Yes, it's a complete drop-in replacement designed for the CZ Scorpion EVO 3 family, including S1, S2, pistol, and carbine models. It doesn't require any of your factory internals to function and can even replace an existing aftermarket trigger group. Most people report the swap takes around 15 minutes.
What does binary mode actually do?
In the binary setting the trigger fires one round when you pull it and a second round when you release it, which effectively doubles your practical rate of fire. It's what makes this the fastest semi-auto trigger available for the Scorpion. If you don't want that second shot, just switch back to the semi position and release the trigger safely.
Does the BFSIII CZ-C1 come with an ambidextrous safety?
It does. The unit ships with an ambidextrous safety selector, so the install also handles a factory safety upgrade at the same time. Both left and right-handed operators get the same clean three-position operation.
What's the trigger pull weight and how is it built?
The BFSIII CZ-C1 runs a pull weight of roughly 4.5 pounds. It's built in the USA with a steel trigger group and a curved trigger shoe that keeps the feel close to the factory setup. That combination gives you both durability and a familiar finger position.
