Keeping Traditions Alive Since 1953
Secure Transactions provided with 
Rimfire cans live a rough life. The ammo is filthy, the round counts pile up fast, and a suppressor that can't be torn down for cleaning eventually turns into a lead-caked paperweight. Dead Air built the Mask-22 HD around that reality. The whole baffle stack comes apart down to the last baffle using the included end cap tool, so a weekend of high-volume plinking never turns into a maintenance headache. That serviceability, more than any single spec, is why this can has stayed one of the best-selling rimfire suppressors on the market year after year.
The tube is Grade 9 titanium (3Al-2.5V) to keep weight down, while the baffles and end cap are 17-4 PH stainless steel where the abuse happens. The result is a can that weighs just 6.6 ounces and measures 5.1 inches long with a 1.070 inch diameter, wrapped in a black Cerakote finish that shrugs off handling, solvents, and field wear. It's full auto rated for .22 LR with no barrel length restrictions, and the caliber rating runs from .22 LR up through .22 Mag, 17 HMR, 17 WSM, and 5.7×28 within its 850 ft-lb energy ceiling.
Plenty of rimfire suppressors sound great on shot two but bark on shot one. Dead Air engineered the Mask's baffle design to knock out first-round pop on both rifles and pistols, so the report stays consistent from the moment you press the trigger. Metered sound levels land comfortably in hearing-safe territory, which makes this a great can for teaching new folks, backyard pest control, or just enjoying a Ruger 10/22 or Mark IV without ear pro.
Mounting is simple direct thread in 1/2×28, the standard pitch for most threaded rimfire barrels and 5.7×28 hosts like the FN Five-seveN and PS90. At this size and weight, it won't make a lightweight pistol feel nose-heavy or throw off the balance of a trim bolt gun. Thread it on, shoot all day, clean it when you get home. That's the whole pitch, and it delivers.
Yes, and that's one of its biggest strengths. The Mask-22 HD disassembles completely down to individual baffles using the included end cap removal tool, no extra equipment needed. Since .22 LR is dirty ammo and fouling builds up fast, being able to fully strip and scrub the baffle stack keeps performance consistent over thousands of rounds.
It handles .22 LR, .22 Magnum, 17 HMR, 17 WSM, and 5.7×28, with an energy ceiling of 850 ft-lbs. Full auto use is approved for .22 LR, while the other calibers are semi-auto rated. That 5.7×28 rating makes it a solid pick for FN Five-seveN and PS90 owners too.
Very little to none, which is a big part of its reputation. First-round pop happens when oxygen trapped inside a suppressor ignites on the initial shot, making it louder than the ones that follow. Dead Air designed the Mask's baffle configuration specifically to eliminate this on both pistol and rifle hosts, so shot one sounds just like shot fifty.
Yes. There's no minimum barrel length requirement, so it runs fine on compact rimfire pistols like the Ruger Mark series or Taurus TX22 as well as full-length rifles. Just make sure your host barrel is threaded 1/2×28, or grab a thread adapter if your setup uses a different pitch.
