Odin 22 Arc 16 Dmr Xl-Rifle Gas System

The Odin Works 22 ARC 16 DMR XL-Rifle Gas System barrel transforms your AR-15 into a precision intermediate rifle capable of serious performance. Built on the 22 ARC cartridge platform, this stainless steel barrel pairs modern high-BC bullet design with the compact AR-15 form factor—delivering accuracy and velocity that rival larger cartridges while keeping your platform nimble and controllable. Whether you're building a designated marksman rifle, hunting medium game, or pushing precision at distance, the 22 ARC 16 DMR gives you capability without compromise.

The engineering behind 22 ARC followed the same proven methodology as the acclaimed 6mm ARC: cartridge and chamber designed in unison for consistent accuracy, tight velocity spreads, and real-world reliability. This isn't a quick adaptation of an existing round—it's purpose-built for modern ammunition like the 62 gr. ELD-VT, which unlocks the ballistic potential this system was engineered for. The result is a rifle that shoots flat, holds velocity downrange, and groups tight from the box.

This Odin barrel ships complete with a tunable gas block and XL rifle gas tube, so you can dial in your specific load and setup without hunting for parts. The 1/2-28 muzzle threads accept standard suppressors and brakes, while the 1:7 twist stabilizes a wide range of 22 ARC projectiles. Odin backs the accuracy with a 1 MOA guarantee—proof that this isn't just a cartridge concept, it's a finished system.

Frequently Asked Questions

What is 22 ARC and how does it perform?

22 ARC (Advanced Rifle Cartridge) is a modern intermediate cartridge designed to fit the AR-15 platform while delivering performance comparable to the 22-250. It was engineered specifically to work with high-BC bullets like the 62 gr. ELD-VT, giving you flat trajectory and velocity retention suitable for hunting, precision shooting, and distance work.

What ammunition works with the 1:7 twist?

The 1:7 twist is optimized for the modern high-BC projectiles the 22 ARC was designed around. We recommend confirming your specific load choice, but this twist rate delivers consistent accuracy with 22 ARC ammunition across the spectrum of available bullets.

What's included and what do I need to complete the build?

This barrel comes complete with a tunable gas block and XL rifle gas tube, so you have the core gas system ready to install. You'll still need a bolt carrier group, charging handle, handguard, lower receiver, and furniture to complete your rifle build.

Can I use a suppressor on this barrel?

Yes. The barrel features 1/2-28 muzzle threads, which accept standard suppressors, flash hiders, and muzzle brakes designed for this thread pattern.
