Franklin Armory BFSIII AK-C1 Binary Firing System Trigger - Curved - 03-50000-BLK
Product Description
Upgrading a classic Kalashnikov pattern firearm for high-velocity indexing, intense dynamic target suppression, or premium tactical competition transitions introduces an immediate mechanical and engineering bottleneck: long, heavy, non-adjustable mil-spec trigger breaks. Standard AK factory triggers are notoriously plagued by gritty, loose trigger take-up, sluggish hammer resets, and a long structural trigger travel arc that severely slows down split times and ruins intermediate tracking accuracy. The **Franklin Armory® BFSIII® AK-C1 Binary Firing System** completely eliminates these platform vulnerabilities, dropping an elite, three-position match-grade trigger engine built straight to aerospace structural tolerances into your AK lower framework.
Precision-engineered in the United States and crafted from heat-treated premium carbon structural steel alloys, this original equipment manufacturer (OEM) conversion kit brings unprecedented cycling velocity to your platform. Unlike basic aftermarket trigger links that only clean up a single stage, the AK-C1 features Franklin Armory’s patented, digital-smooth **Binary Firing System (BFS)** logic. In Position 3 (Binary Mode), the rifle fires one round on the pull pull stroke and a secondary round on the manual release release stroke. By utilizing this dual-activation cycle, the system effectively cuts your mechanical split times in half, allowing operators to run heavy 7.62x39mm or 5.45x39mm platforms at near-cyclic limits with outstanding structural stability.
In high-stakes training drills or demanding multi-gun matches, the advanced safety engineering of the **BFSIII AK-C1** provides a massive weapon-handling advantage. Safety rules remain paramount: if an operator fires on the pull stroke but decides to cancel the subsequent release round, they simply hold the trigger down firmly and toggle the custom selector lever back into standard semi-automatic or safe positions. This allows the trigger to be released safely on your bench without discharging. Outfitted with an authentic, comfortable curved trigger bow profile that mimics classic military layouts while delivering a crisp, uniform 4.5-pound custom break, this premium fire control group replaces sluggish cycling glitches with pure mechanical authority.
*Armorer Bench Notes & Technical Assembly Guidance: The Franklin Armory BFSIII AK-C1 (SKU: 03-50000-BLK) features a direct-fit modular design, making it natively cross-compatible with standard **stamped receiver AK-47, AK-74, and AKM pattern platforms** using standard 5mm receiver axis pins. CRITICAL GEOMETRIC & LEGAL NOTE: This system will require minor fitting or filing along the safety selector bar depending on whether it is being dropped into a Century Arms, PSA, or European import receiver frame. It will physically fail to drop cleanly into proprietary milled receivers, Yugo M70 patterns, or Saiga shotguns without deep gunsmith alterations. When installing on your workbench, verify that you are utilizing the included custom-profile ambidextrous safety selector levers. Always perform a rigorous dry-fire safety function check on an empty bench across all three selector steps before live-firing to ensure the trigger interceptor latch hooks match the hammer timing cleanly. Keep the disconnector notches lightly coated with high-velocity synthetic grease to preserve a smooth pull stroke.
Key Features
- Patented Binary Firing Logic: Features a high-speed three-position trigger system that fires one cartridge on the physical pull stroke and one cartridge on the release stroke for lightning-fast splits.
- Instant Release Round Cancellation: Allows shooters to completely abort the second release round by holding the trigger depressed and manually toggling the safety lever into standard Semi mode.
- Crisp 4.5 lb Match Pull Weight: Features custom-tensioned hammer and trigger springs to replace standard gritty military pulls with a crisp, uniform match-grade wall break.
- Ambidextrous Safety Selectors: Ships complete with tailored, heavy-duty ambidextrous safety selector bars to seamlessly actuate Safe, Semi, and Binary settings from either side.
- Heat-Treated Steel Construction: CNC-machined from high-tensile structural steel alloys with a wear-resistant black oxide finish to prevent sear erosion over thousands of high-velocity rounds.
