Let’s Talk About Franklin Armory BFSIII HK-C1 Trigger – Binary Firing System for HK 91/93/MP5
The Franklin Armory BFSIII HK-C1 Trigger – Binary Firing System for HK 91/93/MP5 promises to transform your HK platform into a rapid-firing beast. This innovative trigger system from Franklin Armory allows for semi-automatic and binary firing modes, potentially doubling your rate of fire. Is it worth the hefty price tag and potential legal considerations?
I’ve always been fascinated by the engineering behind rapid-fire systems and the challenge of maintaining control and accuracy. My interest in the Franklin Armory binary triggers started when I saw some videos of them being used in AR platforms. I needed to see how they perform in the roller delayed blowback system of the HK91/93/MP5.
Unboxing the BFSIII HK-C1 was a promising start. The trigger pack felt solid and well-machined, hinting at the quality I expected for the price. It’s heavier than a standard HK trigger pack, but that weight contributes to the impression of robust construction.
I considered other options, including custom trigger jobs and even some of the full-auto conversions (legally, of course, pre-86 guns!). Ultimately, the binary system offered the best of both worlds: the ability to maintain semi-auto functionality with a burst of speed when desired. It’s a much more accessible and legal alternative to a machine gun conversion.
My initial excitement was tempered with a healthy dose of skepticism. Could it live up to the hype and provide a reliable, controllable, and genuinely fun shooting experience? The possibilities were intriguing, but the performance had to match the promise.
Real-World Testing: Putting Franklin Armory BFSIII HK-C1 Trigger – Binary Firing System for HK 91/93/MP5 to the Test
First Use Experience
My first outing with the Franklin Armory BFSIII HK-C1 Trigger was at my local outdoor range. I installed it in my PTR 91 clone. The weather was mild, with a slight breeze – perfect conditions for testing.
The semi-auto function felt crisp and clean, similar to a tuned HK trigger. Switching to binary mode, however, was a completely different experience. The initial “pull-and-release” firing took some getting used to, as the timing had to be learned to maintain control.
The biggest surprise was the ammo consumption. Binary mode turns your magazine into a disposable item. I quickly realized the importance of controlled bursts to avoid wasting ammunition and overheating the rifle.
Extended Use & Reliability
After several range trips and a few hundred rounds, the BFSIII HK-C1 has proven to be surprisingly reliable. I experienced no malfunctions directly attributable to the trigger system. I do, however, experienced failures related to the PTR91 platform.
Durability seems excellent. There are no signs of unusual wear on the trigger components. Cleaning is straightforward, requiring only basic disassembly and lubrication similar to a standard trigger pack.
Compared to my previous experiences with tuned HK triggers, the BFSIII offers a vastly different experience. While a tuned trigger prioritizes precision and smoothness in semi-auto, the BFSIII adds a new dimension of rapid fire capability. However, a tuned trigger will offer far better accuracy.
Breaking Down the Features of Franklin Armory BFSIII HK-C1 Trigger – Binary Firing System for HK 91/93/MP5
Specifications
The Franklin Armory BFSIII HK-C1 Trigger – Binary Firing System for HK 91/93/MP5 boasts several key specifications that contribute to its unique functionality. It features a traditional curved trigger shape. It also comes with a 4.5 lb trigger pull weight.
It is specifically designed for Heckler & Koch HK93, Heckler & Koch HK91, and Heckler & Koch MP5 platforms, as well as most clones. The trigger offers three distinct positions: safe, semi-automatic, and binary. These specifications are crucial for understanding its performance and intended use.
Performance & Functionality
The Franklin Armory BFSIII HK-C1 Trigger does exactly what it promises: it delivers a functional binary firing system for HK platforms. In semi-auto, the trigger feels comparable to a tuned HK trigger, providing a clean break and reasonable reset.
The binary mode is where it shines (and consumes ammo). The rate of fire is significantly increased. However, it does require practice and discipline to control effectively.
The biggest weakness is the learning curve associated with the binary mode. Overcoming this takes practice. Mastering trigger control is key to avoiding accidental double taps or wasted rounds.
Design & Ergonomics
The BFSIII HK-C1 is built with robust materials and a design that closely mimics the original HK trigger pack. This ensures a relatively straightforward installation process. The weight is noticeable but doesn’t negatively impact the overall handling of the firearm.
The selector switch is easy to manipulate, although some users have noted that the detent could be more positive. The ambi safety selector is a welcome feature. It enhances ergonomics for both right- and left-handed shooters.
Durability & Maintenance
The Franklin Armory trigger appears to be built for long-term durability. The components are well-machined and show no signs of premature wear after several hundred rounds. Maintenance involves basic cleaning and lubrication, similar to any other trigger system.
The design allows for relatively easy disassembly for cleaning and inspection. This further ensures its longevity and reliable performance. Regular maintenance will help keep this trigger system running smoothly.
Accessories and Customization Options
The Franklin Armory BFSIII HK-C1 Trigger doesn’t require any specific accessories for operation. However, high-capacity magazines are essential for maximizing the fun in binary mode.
It is compatible with most standard HK-pattern trigger housings. However, note that trigger housing, ejector, ejector pin and ejector spring are not included. There are no direct customization options for the trigger itself, but its compatibility with various HK platforms and accessories allows for broader customization of the firearm.
