Details

This 18-inch .308 Winchester carbon fiber barrel is a great choice for hunting or backpacking as the light weight will make the rifle all but disappear in your hands or backpack. But don’t let the light weight fool you. This barrel is just as durable as standard steel barrels. With exceptional cold-bore accuracy, you will be able to make the first shot count. Thermal diffusion after long strings of fire is extremely important with carbon fiber barrels and Proof Research uses a helical wrapping pattern of the carbon fibers to effectively dissipate heat from the core of the barrel instead of insulating it. The core is a full profile match grade 416R stainless steel barrel turned down significantly and then wrapped with a high-strength, aerospace-grade carbon fiber that has been mixed with a composite resin.

Features:
  • 64% lighter than traditional steel barrels
  • Match-grade accuracy
  • Improved heat dissipation for cooler and longer lasting barrels
  • 416R Stainless steel barrel wrapped in carbon fiber
  • No point of impact shift during high volume of fire
  • Reduced harmonic barrel vibration
  • Extremely durable
  • Approved for use by United States Military
  • Length: 18”
  • Twist rate: 1:10
  • Caliber: .308 Win

The Proof Research AR10 carbon fiber barrels provide a lighter weight, extremely accurate, and durable alternative to the standard steel barrels. The hard-hitting nature and ballistics of the .308 cartridge make this an excellent choice for hunting. Proof research is able to accomplish such high quality by combining advanced composite materials and thermo-mechanical design principles with a unique manufacturing process and the result is a barrel that weighs a fraction of steel barrels while prolonging barrel life. 

This barrel, along with the many other options to choose from, will dramatically reduce the weight of your rifle whether you are using it for hunting, competitive long-range precision shooting, or even using it as a duty rifle. The firearms industry is in dire need of innovation and Proof Research is leading the way.

Proof research is committed to building the highest quality barrels on the market that can withstand tough environments while still maintaining accuracy and reliability. Their rigorous quality control and manufacturing processes ensure that every barrel that leaves their facility is up to the standards that are expected of a company of this magnitude. Their Quality barrels are a result of more than just precision manufacturing, they are an outcome from countless hours researching and developing resins, adhesives, and composite materials for the aerospace and defense industries. This level of dedication is proof that Proof Research is the best option for a lightweight, durable, and accurate rifle build.
