Rimfire suppressors have a reputation for being either quiet or easy to clean, rarely both. The Dead Air Mask HD manages to pull off the two at once, which is a big part of why it became one of the most popular .22 cans on the market. At just 5.1 inches long and 6.6 ounces, it disappears on the end of a pistol or rifle, and the bead-blasted silver finish gives it a clean, classic look that pairs nicely with stainless barrels.
The tube is Grade 9 titanium to keep weight down, while the baffles are machined from 17-4 PH stainless steel so they can take a scrub, a soak, or an ultrasonic bath without complaint. That matters because .22 LR is filthy ammo, and lead buildup is just part of owning a rimfire can. When it is time to clean, the included end cap tool gets you in, the baffles slide out, and everything clicks back together without any fussy indexing. Owners regularly point to the Mask as one of the easiest rimfire suppressors to service, and the cleaning intervals are generous compared to most of the competition.
The Mask HD is rated for .22 LR, .22 Magnum, .17 HMR, .17 WSM, and 5.7×28, with full auto approved on .22 LR. There are no barrel length restrictions either, so it is just as happy on a short pistol as it is on a 16 inch rifle. The 1/2×28 direct thread mount fits the vast majority of threaded rimfire hosts, from a Ruger 10/22 or Mark IV to a CZ 457 or Taurus TX22.
One detail worth calling out is first round pop, or the lack of it. Dead Air engineered the Mask to minimize that louder initial shot on both pistols and rifles, which is something a lot of rimfire cans struggle with. Add in Dead Air's lifetime warranty against manufacturing defects, and this is the kind of suppressor you buy once and run hard for years.
Yes. The Mask HD is rated for .22 LR, .22 Magnum, .17 HMR, .17 WSM, and 5.7×28 within its energy ceiling. It is also full auto rated on .22 LR, with the other calibers approved for semi-auto use. As long as your host has a 1/2×28 threaded barrel, you are set.
Use the included end cap tool to remove the front cap, and the baffles slide right out for cleaning. The 17-4 PH stainless baffles hold up well to solvent, ultrasonic cleaners, or a good old-fashioned scrub. Reassembly is a simple click-together design with no special indexing required, and it is a good habit to clean it every few hundred rounds since rimfire ammo runs dirty.
No, there are no barrel length restrictions on the Mask HD. You can run it on a compact rimfire pistol or a full-length rifle without any concerns. That flexibility is one of the reasons it works so well as a do-everything rimfire can.
Very little to none, and that is one of its standout traits. First round pop happens when oxygen trapped inside a suppressor ignites on the initial shot, making it noticeably louder. Dead Air designed the Mask specifically to minimize this on both pistols and rifles, which is something many competing rimfire suppressors cannot claim.
