Now Available: PROOF Research 22 ARC Carbon Fiber AR Barrels

Now In Stock – 18" and 20" Models, Fully Verified and Ready to Ship

The next evolution in precision AR performance is here. We’ve officially added PROOF Research’s Carbon Fiber-Wrapped 22 ARC barrels to our lineup—and the first lengths are in stock and ready to ship.

Currently available in 18" and 20", these barrels offer incredible balance between precision, thermal control, and weight reduction. Whether you're chasing predators or ringing steel at distance, these barrels deliver the performance the 22 ARC was made for.

Built by PROOF. Verified by Ally.

We don’t list a single barrel until it passes our internal inspection process. That includes:

• Dimensional checks

• Borescope inspection

• Visual QC

• Fitment validation with known-good carriers and components

Prior to release, we ran sample barrels across multiple factory 22 ARC loads using suppressed, traditional baffled, and flow-through suppressors to confirm gas behavior, reliability, and accuracy. Results were excellent across the board.

When you buy from Ally, you're not just getting a barrel off the shelf. You're getting one that’s been tested, verified, and paired with a matched gas tube for seamless installation.
