KNS Precision® Enhanced AK-47/74 Fire Control Pins – Premium Alloy Steel – Smooth Black Nitride – KNS-AK-TH-EN
The KNS Precision® Enhanced AK/Galil Trigger and Hammer Pin Set (KNS-AK-TH-EN) represents a high-efficiency, premium engineering advancement in critical internal small parts, masterfully built to maximize fire control group longevity and optimize hammer rotation acoustics inside Kalashnikov-pattern firearms. While generic ComBloc (Communist Bloc) military-surplus receiver pins rely on relatively loose structural dimensional tolerances, rough centerless-ground surface paths, and basic phosphate coatings—frequently introducing gritty friction into your trigger take-up lines, or causing accelerated, uneven pin-bore wall ovalization inside soft stamped sheet-metal receivers—KNS Precision completely overhauls internal axis mechanics. This specialized two-piece hardware upgrade (853906008553) transforms basic internal pivot points into an ultra-tough, friction-free foundation for ultra-crisp trigger response and absolute drop-safe engagement cycles.
The structural foundation of these enhanced fire control pins is precision-machined from a monolithic stock of premium, gun-quality high-alloy steel. Chosen specifically for its superior shear strength, resistance to rotational torque fatigue, and defense against impact indentation, this weapons-grade steel matrix ensures the pins never bow, bend, or groove under the constant, punishing forward slap delivered by heavy braided-wire AK hammer springs. The defining technical edge of the KNS-AK-TH-EN configuration is its mirror-smooth liquid Black Nitride surface finish. This advanced technical bath treatment doesn't just seal the underlying steel from sweat and ambient field moisture; it hardens the outermost molecular boundaries to dramatically slice friction coefficients, allowing the hammer and trigger sleeves to rotate around their axis lines with slick, uninterrupted linear uniformity.
The true operational highlight of this tactical hardware upgrade lies in its universal platform cross-compatibility and effortless drop-in logistics. Engineered with exact factory outer dimensions (**~0.195" diameter and 1.42" structural pin length**), the set features cleanly turned positioning grooves that lock seamlessly with standard AK shepherd's hooks or modern multi-layer trigger/hammer pin retaining plates. This high-tier component functions as a direct structural replacement across **standard stamped or milled AK-47, AK-74, and AKM receivers, as well as classic Galil models (including MAR, ARM, and SAR variants)**. Weighing an ultra-optimized 0.39 ounces for the pair, this American-made hardware solution delivers total mechanical authority for gunsmiths, builders, and hard-use tactical marksmen demanding peak operational consistency from their rifle core.
Includes: (1) KNS Precision Enhanced AK/Galil Hardened Alloy Steel Trigger Pin, (1) KNS Precision Enhanced AK/Galil Hardened Alloy Steel Hammer Pin (Both Finished in Low-Friction Black Nitride), and Original Factory Protective Cardboard Retail Presentation Packaging.
*Fire Control Retainer Installation & Alignment Safety Guidance: To secure flawless operational safety loops and prevent dangerous pin walking out of your receiver flats under live fire, always ensure your internal retaining wire or plate is properly seated inside the pin grooves. When driving out your old ComBloc hardware, use a dedicated polymer punch to avoid marring your outer receiver finish, and lightly lubricate the slick nitride outer walls prior to final staging to allow for smooth cross-bore travel.
Key Features
- Slick Black Nitride Hard-Coating: Premium technical surface treatment slashes rotational friction vectors to noticeably smooth out trigger take-up and reset strings.
- Premium American Alloy Steel Core: High-tensile, heat-treated steel alloy completely prevents pin bending and surface grooving under intense, high-volume fire strings.
- Protects Stamped Receiver Walls: Precision-ground round dimensions distribute hard spring pressures evenly, preventing pin-hole wall stretching or ovalization over time.
- Universal ComBloc Cross-Compatibility: Purpose-built to drop straight into standard 4.76mm (~0.195") pin holes across AK-47, AK-74, AKM, and classic Galil rifle frames.
- Perfect Retainer Groove Geometry: Micro-machined locking channels align flawlessly with factory shepherd's hooks or aftermarket modular steel retaining plates.
- Proudly Made in the USA: Precision-machined, treated, and vetted under strict quality controls by the internal firearm specialist team at KNS Precision (Fredericksburg, TX).
