The Dead Air Mask HD FDE is a direct-thread rimfire suppressor finished in flat dark earth Cerakote (Dead Air part no. MASK22FDE). Dead Air Silencers builds it from a Grade 9 titanium tube and 17-4 PH stainless steel baffles, and designs it to come apart easily for long intervals between cleanings. The company describes little to no first-round pop on both rifles and pistols. It measures 5.1 inches, weighs 6.6 ounces and carries a full-auto rating. The FDE version suits a rimfire owner who wants this heavy-duty .22 can in an earth tone rather than black.

Key Specifications

• Dead Air rates it for .22 LR, .22 Magnum, .17 HMR and .17 WSM up to 5.7×28, so one can covers most rimfire and small PDW hosts.
• The energy rating is 850 ft-lbs, the ceiling Dead Air publishes for the Mask HD.
• Bore diameter is .22 caliber, matched to the rimfire cartridges it is rated for.
• Length is 5.1 inches, short enough for most rimfire rifles and pistols.
• Diameter is 1.070 inches, a slim tube that stays close to the barrel.
• Weight is 6.6 ounces, which keeps the muzzle light.
• The tube is Grade 9 titanium (3Al-2.5V), a strong and light tube material.
• The baffles are 17-4 PH stainless steel, which hold up to repeated cleaning.
• The finish is FDE Cerakote, one of the three finishes Dead Air lists for the Mask HD.
• Mounting is direct thread, so it screws straight onto a threaded rimfire barrel.
