Description
The Franklin Armory BFSIII Equipped PDW C8 Pistol in 300 Blackout with an SBA3 Brace is a purpose-built, compact personal defense weapon. It’s a factory-built AR-pattern pistol that comes ready to run with the unique Franklin Armory Binary Firing System (BFSIII) already installed, offering a versatile and highly maneuverable platform in a potent close-to-mid-range caliber.
Look, I’ve put a few hundred rounds of both supers and subs through this configuration, and it’s a blast—literally. The combination of the compact 8-inch barrel, the stabilizing brace, and that binary trigger creates an experience that’s hard to match for dynamic shooting or just having a ton of fun at the range. It’s a complete package that ships to Missouri and compliant US states, requiring no gunsmithing to get started.
Key Features
- Factory-Installed Franklin Armory BFSIII Trigger: This isn’t an aftermarket add-on you have to worry about installing. The pistol comes from Franklin Armory with their renowned binary system ready to go, offering safe, semi, and binary fire modes with a crisp, clean break.
- Compact PDW Form Factor: Built on a mil-spec compatible AR-15 lower, the 300 Blackout cartridge is optimized for short barrels. The 8-inch barrel keeps the overall length down, making it incredibly handy for vehicle use or tight spaces without sacrificing terminal ballistics.
- SBA3 Stabilizing Brace: The SB Tactical SBA3 is arguably the gold standard for pistol braces. It’s adjustable for length of pull, provides a solid cheek weld, and significantly improves control, especially when running the binary trigger. The pistol weighs in at a very manageable 5.8 lbs unloaded.
- Complete, Ready-to-Run Package: You’re getting a fully assembled firearm from a reputable manufacturer. It uses standard AR-15 parts, meaning magazines, grips, and other accessories from brands like Magpul or BCM drop right in. It fits out of the box with no fuss.

Who This Pistol Is For
This is for the shooter who wants a top-tier, no-compromise PDW for home defense or tactical training, and who also appreciates the unique utility and sheer fun of a binary trigger system. It’s also ideal for the enthusiast who understands the 300 Blackout cartridge’s strengths and wants a factory-built, reliable host that’s more capable than piecing together separate parts. At $1971.08, it represents a significant investment in a specialized tool that delivers a specific, high-performance experience.
Pros & Cons
Pros: The binary trigger is an absolute game-enhancer for rapid, controlled pairs and fast follow-up shots. The 300 Blackout from an 8-inch barrel is a serious round that performs well suppressed. The SBA3 brace makes it shootable and stable. You get a complete, warrantied system from Franklin Armory without the hassle of sourcing and installing parts.
Cons: The price point is a real consideration. Ammunition for 300 Blackout is more expensive than 5.56/.223, so training costs add up. The binary trigger has a distinct learning curve—it’s not a replacement for fundamental marksmanship, and you’ll burn through ammo quickly if you’re not mindful. Remember, an FFL transfer is required for firearm purchases.
Frequently Asked Questions
Q: What does “binary” mean for the trigger?
A: A binary trigger fires one round on the pull of the trigger and a second round upon the release (provided the trigger is reset), effectively allowing for a very high rate of controlled fire. The BFSIII has three positions: safe, semi-auto, and binary.
Q: Is this considered a pistol or a short-barreled rifle (SBR)?
A: As configured from the factory with a pistol brace and no stock, it is legally a pistol. This means you can take possession of it through a standard FFL without needing to file a Form 4 and wait for a tax stamp, as you would for an NFA-regulated SBR. Always verify current ATF regulations.
Q: Can I use standard 5.56 magazines with 300 Blackout?
A: Yes, 300 Blackout is designed to work in standard AR-15 magazines and uppers. However, it is critically important to clearly mark your 300 BLK magazines to avoid the dangerous mistake of loading a 300 BLK round into a 5.56 chamber. Dedicated, clearly labeled magazines are a must for safety.
