Dead Air Mask 22 HD
The Dead Air Mask 22 HD is a direct-thread rimfire suppressor rated
for .22 LR, .22 Magnum, 17 HMR, 17 WSM, and 5.7x28. It weighs 6.6
ounces, measures 5.1 inches in length, and is built from a Grade 9
titanium tube with 17-4 PH stainless steel baffles. It is full-auto
rated for .22 LR with no barrel length restrictions.
Most rimfire suppressors make a compromise somewhere. The Mask 22 HD
does not. Dead Air built it to lead the category on sound suppression,
materials quality, and user serviceability from day one.
The Grade 9 titanium tube keeps total weight at 6.6 ounces without
sacrificing durability. The 17-4 PH stainless steel baffles tolerate
aggressive cleaning methods including brushes and ultrasonic tanks,
which aluminum or lower-grade steel baffles cannot withstand. The
click-together baffle stack uses proprietary external standoffs that
minimize contact with the tube wall, so the baffles slide out cleanly
even after heavy fouling. Rimfire ammunition is inherently dirty. The
Mask 22 HD is built with that reality in mind.
Sound suppression is consistently rated among the best in the rimfire
category. The Mask 22 HD produces little to no first-round pop on both
rifles and pistols. First-round pop occurs when oxygen trapped inside
the suppressor combusts on the initial shot, producing a
louder-than-normal report. The Mask 22 HD eliminates this on both rifle
and pistol hosts, making it one of the few rimfire cans that perform
equally well across platforms.
