Faxon®'s Pencil Barrels are among the best and lightest in the industry, offering the ideal balance of weight and performance. That's why premier AR manufacturers like 2A Armament® and Robar® have trusted Faxon Barrels for years.

Each Faxon Barrel is manufactured 100% in-house from mil-spec 4150 certified gun barrel steel. From there, each Barrel is then fully stress-relieved, air gauge-tested, and 11º target-crowned for superior accuracy. Finally, each one goes through meticulous testing before being finished in nitride. That means you can count on the highest level of performance in the lightest possible package.
