KC-02 Threaded Carbon Fiber Spiral Outer Barrel

$79.99

Specify the length you would like the outer barrel to be. This is from the base of the barrel to the tip of the thread.
With a stock hopup, the inner barrel sits recessed by about 3.5mm. So if you own a 250mm Inner Barrel, a 250mm Outer Barrel will be the perfect choice as the inner barrel will sit just inside the tip of the threads.

KC-02 Threaded Carbon Fiber Spiral Outer Barrel Details

KC-02 Threaded Spiral Outer Barrel — Carbon Fiber

Precision 3D Printed Barrel with Spiral Design

Enhance your KC-02 with the Threaded Spiral Outer Barrel, now 3D printed in Carbon Fiber (Nylon PA11 Carbon Fiber composite). This outer barrel pairs a striking spiral aesthetic with engineered strength and dimensional stability—maintaining accurate threads and hop-up seating while resisting wear and heat better than standard Nylon PA12 prints. It includes a 14MM Negative (-14mm) thread for broad accessory compatibility and is optimized to balance durability with low weight for improved handling.

Key Features:

  • 3D Printed Carbon Fiber Construction: Made from Nylon PA11 Carbon Fiber composite for superior stiffness, impact resistance, and thermal stability—ideal for threaded parts that require precise tolerances.
  • Spiral Outer Barrel Design: Distinctive spiral styling that reduces mass while preserving rigidity and adds a tactical, custom look.
  • Thread: 14MM Negative (-14mm) — compatible with a wide range of barrels and suppressor-style accessories.
  • Includes Hop-Up End & Threads: Finished with properly located hop-up seating and threaded mounting surfaces for reliable assembly.
  • Lightweight & Durable: Carbon Fiber composite provides excellent strength-to-weight performance for improved handling.
  • Professional Installation Recommended: Proper fitment and thread torque are important for best results.

Installation Note: Parts printed in composite sometimes show minor shipping curl; this barrel will typically straighten when the inner barrel is installed and properly torqued. Verify fitment and alignment during installation.

Compatibility: Designed for the KC-02 platform — verify dimensions before purchase.

Strength you can feel. Weight you barely notice. Precision that defines performance.
Matte black, rigid, and ready — engineered for those who demand more than plastic.

Unmatched Strength and Rigidity

Up to 38% Higher Tensile Strength – 69 MPa vs. 50 MPa for Nylon 12, giving parts more load-bearing capability.
Nearly 3× Stiffer – With a tensile modulus of 5.3 GPa (vs. 1.9 GPa), PA11 CF parts hold their shape under pressure and stress.
Over 65% Greater Flexural Strength – 110 MPa vs. 66 MPa for Nylon 12 means stronger parts that won’t bend or deform.

Superior Heat and Environmental Resistance

Designed for high-temperature applications where Nylon 12 softens or degrades.
Carbon fiber reinforcement improves thermal stability and lowers thermal expansion for precision even under heat.
Naturally resistant to moisture and UV exposure, ideal for rigorous outdoor use.

Professional Finish and Lightweight Design

Carbon fiber infusion produces a sleek matte black surface — functional and aesthetic right off the printer.
Delivers metal-like strength at a fraction of the weight, enabling lighter, more efficient assemblies.

Designed for High-Pressure HPA systems

Lightweight carbon fiber composite reduces load without sacrificing strength or rigidity.
Tested for durability across extreme temperature and humidity conditions to ensure reliable field performance.

Rigid Carbon Fiber Structure

Low expansion under heat preserves airseal integrity during rapid-fire or sustained full-auto use.
Machined precision surfaces ensure smooth magazine insertion and consistent alignment with feed paths.

Advanced Finishing

Custom Cerakote & Precision Coatings

Our in-house finishing delivers Cerakote and precision laser engraving with exceptional durability and style. Every surface is treated, coated, and inspected to ensure flawless performance and lasting quality.
