New PM-22 Rimfire Silencer From Inland Manufacturing
Russ Chastain 04.12.17
Inland Manufacturing has announced a new sound suppressor for rimfire rifles (it’s .22 caliber but they say it will work with any rimfire… I’m sure they are including the tiny .17s), which they say combines low cost with high efficiency. They’ve dubbed it the PM-22 and will be marketing it through MKS Supply.
The outer tube of the silencer is aluminum and the baffle core is plastic. The core can be replaced, but only by the manufacturer. I has been tested to 10,000 rounds so far without need for replacement. Interesting.
They have this to say about it:
Materials: The all-new PM-22 suppressor is constructed of 6000 series aluminum and weighs a feathery 3.5 ounces, making it one of the lightest such units on the market. The black anodized, one-inch-diameter tube is 5.5 inches long. For durability, the ½ x 28 threaded base adapter is stainless steel with a tough black oxide finish.
Interior sound baffles: The PM-22 uses a unique monolithic,
X-design polymer baffle system core that can be used either “wet” or dry. Full disassembly can be completed without tools, and cleaning is simple using hot water and Inland’s dB Suppressor Foam which can further reduce most suppressor’s sound 3-10 decibels.
Rimfire ammunition creates lower gas pressure, heat and flame than does centerfire ammunition. Inland’s patent pending polymer baffle system has been tested to 10,000 rounds (so far) without needing replacement. If baffle replacement does become necessary, the PM-22 has a lifetime warranty (NFA replacement and shipping rules apply).
Facts concerning this suppressor: Polymer baffles have less inherent harmonic metallic resonance than metal and they are produced using injection molding rather than with much more costly metal machining. This keeps the price lower.
Sound: The Inland suppressor keeps the decibel level in the low to mid-80s using subsonic ammunition and when shot dry. When combined with Inland’s patent pending sound suppressing dB Foam, the sound is reduced another 3-5 decibels (a 4-ounce can of dB Foam is included with each suppressor). To say it another way, with subsonic ammunition, only the functioning of the pistol’s action is audible from more than a few yards away.
