The Dead Air Mask HD is a compact, heavy-duty .22-caliber suppressor engineered for excellent sound reduction, minimal first-round pop, and straightforward maintenance. Its combination of a lightweight Grade 9 titanium tube and durable 17-4 PH stainless-steel baffles provides strength in areas exposed to fouling and heat while keeping the overall weight to only 6.6 ounces.
This FDE model features a direct-thread 1/2x28 mounting system and measures only 5.1 inches long, helping maintain excellent balance on compatible pistols and rifles. Its removable baffle stack allows the suppressor to be disassembled for periodic cleaning—particularly important when firing ammunition that produces substantial lead and carbon buildup.
Although optimized for .22 LR, the Mask HD is also manufacturer-rated for .22 Magnum, .17 HMR, .17 WSM, and 5.7x28mm, subject to a maximum energy rating of 850 ft-lbs. Dead Air lists the Mask HD as full-auto rated with no barrel-length restrictions, making it a compact and versatile option for compatible .17- and .22-caliber hosts.
