BC Custom Carbon Fiber Tensioner for FX Impact M3 w/ FX Clamp, 800mm, .35 Cal - Advanced Performance Enhancement


Optimize your FX Impact M3 with the BC Custom Carbon Fiber Tensioner, specifically designed for the 800mm, .35 caliber barrel with an FX Clamp. This high-quality product, developed in collaboration with Bullet Central and Ernest Rowe, is crafted to significantly enhance the rigidity and stiffness of your airgun's barrel, offering an option to further augment these improvements with an additional shroud.

What Comes with the Tensioner

  • Tension Nut: Essential for securing the tensioner in place, ensuring stability and alignment.
  • Carbon Fiber Tensioner: The main component that directly enhances the rigidity and reduces the overall weight of the barrel.

Optional Upgrade

  • Carbon Fiber Shroud: Available for separate purchase, this shroud increases the stiffness and rigidity of the barrel, enhancing shooting accuracy.

Choosing the Right Tensioner Kit

  • With Clamp: If your FX Impact M3 is equipped with a clamp, select the tensioner kit that includes a clamp to ensure a secure and optimal fit.
  • Without Clamp: For FX Impact M3 models without a clamp, the standard tension kit is appropriate. It is crucial to select the right kit based on your airgun’s configuration for proper installation.

Installation Guide

  1. Prepare the Tensioner: Start by identifying the ends of the tensioner. The end with a recessed cut is designed to point downrange.
  2. Install the Tension Nut: Slide the non-cut end of the tensioner onto the barrel first, moving towards where it will sit. Attach the tension nut to the recessed cut end and tighten it securely using a 2mm Allen key.
  3. Check Alignment: Ensure that the tensioner is properly aligned along the barrel. Correct installation is vital for the tensioner to function effectively, ensuring improved barrel performance.

Benefits of the Carbon Fiber Tensioner

  • Weight Reduction: Made from carbon fiber, the tensioner significantly lightens the barrel, enhancing maneuverability and handling.
  • Increased Stiffness and Accuracy: The tensioner adds considerable stiffness to the barrel, reducing vibrations and flex during shooting, which helps in improving accuracy and consistency.


The BC Custom Carbon Fiber Tensioner for the FX Impact M3, 800mm, .35 caliber with FX Clamp, is an essential upgrade for shooters looking to enhance their rifle's performance. By providing a solid base for barrel stability, this tensioner not only improves the structural integrity of the barrel but also boosts precision and handling. For those seeking even greater performance, the optional carbon fiber shroud represents a worthwhile additional investment, ensuring your FX Impact M3 performs at its best in any shooting scenario.
