Alex Pro Firearms Dmr 22Arc 2.0 18 Magpul Acs White

The Alex Pro Firearms DMR 2.0 in 22 Arc is a purpose-built designated marksman rifle that bridges the gap between precision and practical firepower. Built on a billet receiver set with ambidextrous controls, this 18-inch rifle delivers the ballistic efficiency of 22 Arc in a compact, configurable platform. Whether you're running drills at distance, hunting medium game, or building a versatile AR that handles beyond typical close-quarters duty, this DMR gives you real precision tools without the weight penalty of a full-length hunting rig.

Alex Pro Firearms equipped this build with components chosen for accuracy and reliability. The 416 stainless steel barrel features a 1:7 twist rate optimized for 22 Arc's range of bullet weights, while the diamond-honed M16 bolt carrier group with 6.5 Grendel bolt face ensures smooth, consistent operation. The rifle-length gas system keeps recoil manageable, and the adjustable gas block lets you fine-tune cycling for your specific ammunition or suppressor setup. That matters in a DMR—you want to dial in your gun, not fight it.

The furniture is Magpul throughout: the ACS stock gives you a solid cheek weld and adjustable length of pull, the MOE grip is textured and comfortable, and the 15-inch M-Lok handguard provides real estate for optics and accessories. Up front, the APF Butcher-16 muzzle brake tames recoil and helps you spot your own shots. The 3.5-pound APF drop-in trigger breaks clean, supporting the precision work a DMR demands. Finished in white Cerakote, it's as much a statement as it is a shooter.

22 Arc is gaining ground with shooters who want intermediate-cartridge velocity and efficiency in an AR-15 platform. If you're ready to step beyond 5.56 and explore what a dedicated DMR can do, this build is ready to go to work.

Frequently Asked Questions

What is 22 Arc and why choose it over 5.56 or 6.5 Creedmoor?

22 Arc is an intermediate cartridge designed for modern AR-15 platforms, offering increased velocity and energy compared to 5.56 NATO while maintaining compatibility with standard AR magazines and bolt faces (using a 6.5 Grendel bolt). It delivers effective range and power for hunting and marksmanship at distance without the added recoil or cost of larger calibers, making it a solid choice for marksmen who want to step up without changing their entire platform.

Can I use this rifle with a suppressor?

Yes. The rifle-length gas system and adjustable gas block are specifically designed to work with suppressors. The adjustable gas block lets you tune the cycling to work optimally with your specific suppressor and ammunition combination, giving you the flexibility to dial in the gun for your setup.

Does this rifle come with sights or optics?

No—the DMR 2.0 ships as an optics-ready platform with no iron sights included. You'll need to add your choice of scope, red dot, or magnified optic. The M-Lok handguard provides plenty of real estate for optics mounts and accessories.

What ammunition should I use in a 22 Arc?

We don't have specific ammunition recommendations in our product data. Contact Alex Pro Firearms or check with ammunition manufacturers who produce 22 Arc loads for guidance on compatible bullet weights and types for your intended use.
