Virtually impervious to weather, nicks, dings or scratches, and up to 30% lighter and 300% stiffer than equivalent weight steel AR barrels, PROOF Research’s carbon fiber-wrapped barrels open up new possibilities in AR performance.

  • These carbon fiber-wrapped barrels provide a high-end alternative to traditional barrels while still maintaining extreme accuracy, performance and durability.  
  • Match-grade accuracy
  • Improved heat dissipation for cooler and longer lasting barrels
  • No point-of-impact shift during high-volume fire
  • Reduced harmonic barrel vibration
