Boss Barrels .22 ARC 18" Carbon Fiber Barrel - AR-15 Compatible

Boss Barrels .22 ARC 18" Carbon Fiber Barrel - AR-15 Compatible

Dominate the range and the field with the ultimate fusion of lightweight agility and unyielding precision. Engineered for shooters who refuse to compromise, this 18-inch 22 ARC barrel redefines what is possible in high-performance rifle ballistics. By wrapping a fully stress-relieved, air-gauged 416R stainless steel core in cutting-edge aerospace-grade composite materials, we have stripped away the heavy legacy steel weight without sacrificing an ounce of rigidity or structural integrity.

Whether you are tracking game across rugged terrain or punching tight groups on the competition line, this barrel is built to endure. Thanks to a multi-step manufacturing process and proprietary, thermally conductive matrix blends, heat dissipates rapidly to eliminate thermal drift and maintain a perfectly stable point of impact during rapid fire. Backed by an ironclad Sub-MOA Guarantee, this 22 ARC barrel delivers the confidence you need to make every shot count.

Aerospace Composite Reinforcement
Utilizing advanced, in-house composite technology to achieve a fraction of the weight of traditional steel contours, reducing shooter fatigue while maintaining maximum barrel rigidity.

Premium 416R Stainless Core
Built from a fully stress-relieved and air-gauged stainless blank to ensure match-grade consistency, extreme durability, and exceptional corrosion resistance.

Sub-MOA Accuracy Guarantee
Crafted to meticulous tolerances to deliver sub-Minute of Angle precision, giving you competitive-grade repeatability out of the box.

Proprietary Thermal Management
Employs thermally conductive material blends that quickly draw heat away from the chamber and bore, preventing barrel warp and extending service life.

Optimized 1/7 Twist & 3R Rifling
Engineered specifically to stabilize heavy, high-BC 22 ARC projectiles while minimizing bullet deformation for flatter trajectories and cleaner bullet paths.

Rifle +1 Gas System
Extends the gas system length to smooth out the cycling impulse, significantly reducing felt recoil and internal component wear.

Nitride Coated M4 Extension
Features a match-grade M4 barrel extension treated with a durable nitride finish to ensure flawless feeding and reliable extraction under harsh conditions.
