BC Custom Carbon Fiber Shroud & Tensioner Kit for FX Impact MKI/MKII, 700mm - Advanced Performance Upgrade


Elevate the performance of your FX Impact MKI or MKII with the BC Custom Carbon Fiber Shroud & Tensioner Kit, specifically designed for the 700mm barrel. This kit, crafted in collaboration with Bullet Central and Ernest Rowe, is engineered to reduce barrel weight and enhance stiffness and rigidity, significantly improving accuracy and consistency.

What's Included in the Kit

  • Tension Nut: Vital for securing the assembly, ensuring stability and proper alignment.
  • Carbon Fiber Shroud: Increases the barrel's stiffness, significantly enhancing accuracy while maintaining a lightweight profile.
  • Tensioner: Applies necessary tension to boost barrel rigidity, crucial for consistent shooting performance.

Choosing the Right Kit

  • With Clamp: If your FX Impact MKI/MKII is equipped with a clamp, select the tensioner kit with a clamp to ensure a secure and optimal fit.
  • Without Clamp: For airguns without a clamp, the standard tension kit is recommended. Choosing the correct version based on your airgun’s setup is essential for proper installation and optimal functionality.

Installation Guide

  1. Remove Existing Barrel: Begin by unscrewing and removing the barrel from your FX Impact MKI/MKII.
  2. Identify Tensioner Ends: Locate the end of the tensioner with the recessed cut — this should face downrange when installed. The other end, which is smooth, should slide on first towards the rifle.
  3. Install the Tension Nut: Attach the tension nut to the recessed end of the tensioner. Tighten it securely using a 2mm Allen key to ensure it is firmly fastened.
  4. Attach the Shroud: Slide the carbon fiber shroud over the tensioner. The included O-ring ensures a tight fit, critical for maintaining an effective air seal.
  5. Secure the Shroud: Screw the shroud onto the tensioner nut until it is snug and fully secured, ensuring proper alignment.

Benefits of the Carbon Fiber Tensioner and Shroud

  • Weight Reduction: The use of carbon fiber significantly reduces the overall weight of the airgun, enhancing handling and maneuverability.
  • Increased Stiffness and Rigidity: This upgrade not only adds stiffness to the barrel but also reduces vibrations, enhancing the accuracy and consistency of your shots.


The BC Custom Carbon Fiber Shroud & Tensioner Kit for the FX Impact MKI/MKII, 700mm, is an indispensable upgrade for airgun enthusiasts seeking to optimize their shooting experience. This kit not only improves the structural integrity of the barrel but also boosts precision and handling, making it a valuable investment for competitive shooters and serious hobbyists alike. With its superior design and high-quality materials, this kit ensures your FX Impact airgun performs at its highest potential, delivering reliability and enhanced accuracy with every shot.
