Proof Research 16" Carbon Fiber 22 ARC Barrel - Rifle-Length Gas

Proof Research 16" Carbon Fiber 22 ARC Barrel - Rifle-Length Gas

Step into the future of AR performance with the Proof Research 16″ 22 ARC Carbon Fiber Barrel. Engineered for shooters who demand match-grade accuracy, reduced recoil, and extreme durability, this barrel redefines what’s possible in the AR platform. Featuring Proof’s proprietary Caliber Matched Gas System (CAMGAS), it’s tuned for optimal gas flow and reliability—especially with high-performance cartridges like 22 ARC.

Wrapped in aerospace-grade carbon fiber and built on a match-grade 416R stainless steel core, this barrel is up to 64% lighter than traditional steel, yet tougher and more heat-resistant. Whether you're chasing sub-MOA groups or pushing through high-volume fire, this barrel keeps you on target and running clean.

Ultra-Lightweight Carbon Fiber Construction
Up to 64% lighter than steel barrels of similar contour—ideal for maneuverability and endurance.

Match-Grade 416R Stainless Core
Precision-machined for consistent accuracy and long-term performance.

CAMGAS Tuned Gas System
Caliber-specific port placement ensures smoother recoil, cleaner cycling, and reduced brass wear.

Extreme Heat Dissipation
Carbon fiber diffuses heat along and through the barrel wall, keeping temperatures lower for longer shooting sessions.

No Point-of-Impact Shift
Maintains zero even during high-volume fire—perfect for tactical and competition use.

Reduced Harmonic Vibration
Enhances shot-to-shot consistency and minimizes barrel whip.

Unmatched Durability
Aerospace-grade composite wrap with proprietary matrix resin resists wear, corrosion, and environmental stress.
