Dead Air Xemax Hub Pattern 3/8x24

The Dead Air Xemax Hub Pattern 3/8x24 is a muzzle brake adapter engineered for shooters running big-bore rifles with Dead Air suppressors. This 3/8x24 threaded hub connects your Xemax-compatible muzzle brake to Xemax-pattern suppressors, enabling the precision alignment and repeatability that Dead Air's Xeno mounting technology delivers. Built from 4140HT chromium-molybdenum heat-treated steel and finished in hard-use nitride black, it's designed to handle the pressure and recoil of .33 caliber magnums (.338 Lapua Mag, 8.6 Blackout) and .45 caliber platforms (.45-70, .450 Bushmaster, and big-bore ARs) without compromise.

If you already own a Dead Air Primal silencer, the Xemax adapter lets you retrofit that can to the Xemax system by simply swapping the muzzle brake on your rifle. The self-aligning taper design ensures consistent bore centering shot after shot, which translates to better suppressor performance and extended silencer life—especially important when you're running magnum or specialty cartridges that generate serious heat and pressure. The Xemax single-port brake design vectors gas outward and upward, reducing felt recoil and minimizing the ground dust signature that can complicate shooting from prone or low-angle positions.

Weighing just over 2 ounces and measuring 1.135 inches in length with a 1.540-inch diameter, this hub sits neatly at the muzzle interface. Keep in mind: Xeno and Xemax devices are not cross-compatible, so you'll need a Xemax muzzle brake (not Xeno) on the rifle end. Also verify your suppressor's caliber rating before mounting—not all Dead Air cans are rated for all big-bore cartridges.

Specifications

Frequently Asked Questions

Is the Xemax Hub compatible with Xeno-pattern suppressors?

No. Xeno and Xemax devices are not cross-compatible. You must use a Xemax muzzle brake paired with a Xemax adapter and Xemax-pattern suppressor. If you have a Xeno suppressor, you'll need Xeno mounting components instead.

Can I use this adapter with my Dead Air Primal silencer?

Yes. If you own a Primal silencer, you can retrofit it to the Xemax system by installing this Xemax adapter on the suppressor and mounting a Xemax muzzle brake on your rifle. However, verify your Primal's caliber rating matches your cartridge before assembly.

What calibers does this hub support?

The Xemax system is optimized for .33 caliber rifles (including .338 Lapua Mag and 8.6 Blackout) and .45 caliber platforms (.45-70, .450 Bushmaster, and large-frame MSRs). Always confirm your suppressor's caliber and bore size limitations before mounting this hub.

What's included in the package?

The package includes the Xemax Hub Pattern 3/8x24 adapter only. You'll need a compatible Xemax muzzle brake (sold separately) for your rifle and a Xemax-pattern suppressor to complete the system.
