Inland Firearms Low-Cost PM-22 Rimfire Suppressor

When it comes to National Firearms Act (NFA) controlled items, there’s a weird reverse psychology that goes into purchase decisions. It’s almost as if lower priced items are passed over, especially those that fall in the “under $200”. With silencer popularity skyrocketing, budget minded buyers are not as fazed by pricess that fall under the tax stamp threshold. In this vein, Inland Manufacturing is announcing the $190 PM-22 rimfire suppressor that uses a “replaceable” polymer monocore baffle system.

Polymer inside a suppressor? Sure, why not. heat and pressure levels inside a rimfire can don’t come close to the levels found inside their centerfire brethren. Besides, Inland is boasting a 10K+ round count without needing a factory installed replacement.

When I fall asleep at night, I dream of NFA deregulation, and the ability of every freedom-loving American to experience affordable suppressed shooting. After all, it’s just a tube.

MKS Supply, Inc., Dayton, OH, April 2017 – Inland Firearms, makers of the incredibly popular Inland series of M1Carbines, is now producing a classic-looking sound suppressor for .22 rimfire firearms that will be marketed exclusively through MKS Supply and will be on display at the NRA Convention booth 4632.

  • 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.
  • 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.

The new PM-22 rimfire suppressor is 5.5” overall length and just under 1” diameter. Weighing in at 3.5 oz, it could be one of the lightest suppressors on the market today. The new Inland PM-22 is constructed with an aluminum tube and stainless steel base threaded ½ X 28 TPI. The I-Core polymer monolithic disposable baffle system features the X Baffle system that was designed to be used dry or with the new dBFoamsuppressorfoam for maximum efficiency.

*** UPDATE – Thanks to everyone who pointed out what I should have caught the first time: mid-80dB for a suppressed firearm is virtually impossible.

    “theirs” = “there’s”
    “phased” = “fazed”

  • Dr. Longfellow Buchenrad

    The parable of the refrigerator:

    There was once a man who upgraded his refrigerator. He put his old one out on the street with a sign that said “free please take.” It sat there all week and nobody took it. He then changed the sign to say “$50 inquire within” and while he was gone at work it disappeared.

    The moral of the story is the more you charge for something, the better people think it is. The only thing that counters that is strong competition and the suppressor market still does not have enough volume of sales to have that degree of competition. Im pretty sure if/when the HPA passes and after the market settles we will have $50 cans or even less.

    • iksnilol

      About the equivalent of 350 bucks for a lightweight hunting suppressor (cheapest you can find for a centerfire), rimfire cans are like 150 bucks or so.

      Source: Norway.

      Also, no way you’ll have cans for 50 bucks, unless they’re bulk, rimfire cans from China.

      • Dr. Longfellow Buchenrad

        Just because its bulk from China doesnt mean it wont work. I think (again under theoretical conditions of a stable post-HPA market) that the sheer volume of Americans shooters buying cans in addition to cheap mass produced imports could drive the price down to $50 for an entry level .22 suppressor. When engineering costs and company overhead are split between so many products they can get pretty cheap.

        • iksnilol

          I don’t badmouth China, I just don’t see how you’ll get it so cheap otherwise whilst being useful.

      • TheNotoriousIUD

        If it passes (it wont) there very well may be a disposable can market.

        • iksnilol

          Surprisingly, I doubt it’ll happen like that. Because that’d be like buying cheaper barrels so that you can afford to change them more often.

          • TheNotoriousIUD

            I can totally see people buying cheap throw away cans in America. Its not like theyre super complicated to make especially if its being mass printed by the thousands.
            I cant think of any reason someone wouldnt make a $15 can.

          • Tassiebush

            If I could buy a $15 can every so often it would be a fair while before I’d get round to getting something more durable and expensive. I can sort of imagine a type that you shoot out the appropriate size bullet holes in the baffles. That way it could be one size fits all.

          • Christian Hedegaard-Schou

            People buy dirt-cheap bottom-market barrels all the time, and other bottom-market Chinese imported crap like handguards and lower parts kits even.

          • iksnilol

            Yeah, but I doubt you’d buy a barrel that’ll last only a 1000 rounds because it was cheap.

          • int19h

            A gun won’t function without a barrel. But it will without a suppressor. And a suppressor is easy to remove and install. Apples and oranges.

      • Herr Wolf

        A threaded 22lr suppressor using an e-bay thread adapter, PVC and aluminum fender washers can be made for $10 in materials.

        • iksnilol

          So let’s say you did this… would it make sense for you to sell it for 12 dollars?

          • Juggernaut

            If you could sell it for $30+(.5 hour labor incl.) that would be a he** of a markup

      • Wow!

        The reason why cans are still expensive in Europe is because not as many people are gun owners. The cans may not be regulated, but the firearms are. In America the limiting factor is not the guns but the cans. Silencers are not complex devices. A scope is much more complex yet UTG can crank a pretty good one for just $70. Seeing silencers as low as $50 if not lower for heavier and lower quality, is not an impossible reality.

        • iksnilol

          AHAHhaahaha, you ain’t getting a good scope for 70 dollars.

          • Wow!

            I’ve done the box test, tracking is within 1/4 MOA and the clarity is good as far as 800 yards (haven’t gone further on that setup). You don’t have to pay big bucks to get acceptable quality. Higher price might get you the quality in a smaller package, but UTG compensates by using glass with a wider objective lens and a larger diameter turret to match the tracking of smaller optics. They also are rugged scopes. I got one mounted on a 50 caliber bolt action that has not broken or lost zero after about 400 rounds. I can’t say the same about other “conventional” brands which luckily have good warranties behind them.

            If I did more shooting at dusk, the quality of the higher end scopes would come into play, but all my shooting is daytime and I built an IR module for my LR308 which is my go to outdoors gun, so it kind of compensates for any light gathering deficiencies.

          • TangoVictor

            Good is relative. You can get a UTG Bug Buster for $70-80 and its considered a premium rimfire scope and handles 223/556 no problem. You’re probably not ringing steel at 1000yds with it but it’s “good” for it’s intended purpose 😉

          • Wow!

            There are two ways to build a scope (much like building suppressors), you can make a cheap optic but very big and bulky to achieve greater performance, or you can go small and light for a premium price tag. One advantage to UTGs massive scope size is that they are very durable. I have one on a 50bmg bolt action and it has not lost zero (on a larue 50bmg mount that came with the rifle, lol) in a good couple hundred rounds. Of course, I agree that UTG won’t go toe to toe with more expensive optics in the large bore competitions (which shoot in excess of a mile), but the reality is that no one (not even mil or le) will ever see that outside of very niche competition events. Even if target ID is a concern, generally that is done by another component of your force, not by the rifle scope which no matter how clear it is, mirage will keep you from properly ID a target with enough distance.

            EDIT: actually scratch that last part, I can think of some areas where the mirage probably wouldn’t impair clarity.

    • M.M.D.C.

      “Im pretty sure if/when the HPA passes and after the market settles we will have servicable $50 cans or even less.”

      It does seem strange that a relatively simple suppressor would cost the same or more than a pistol.

    • BryanS

      If the HPA passes, I can build my own, as I can any other firearm, without the tax stamp.

      Expect the cost of dorman stamped freeze plugs to go up.

      And hell, if polymer works for 22, Why not have a hand at printing baffles? You could at least get a good piece for casting out of one.

      • Juggernaut

        A 3D printed disposable can for 22lr is already doable, is it not?

    • wetcorps

      France here. Once you jumped the hoops to get guns, suppressors aren’t more regulated.
      The cheapest rimfire suppressors are 25€ to 30€. Most seem to do an OK job with subsonics. When people want better rimfire suppressors they go for more expensive stuff in the 50-100€ range and seem very satisfied with them.
      Centerfire suppressors are another story, some are indeed a few hundreds. From a quick search the most expensive I could find is a 700+ Brugger & Thomet. The cheapest centerfire suppressors seem to be in the 200€ range.

    • Colonel K

      $50 for little aluminum .22 cans in New Zealand.

  • Graham2

    I could be wrong of course (it has happened!) but from what I can see from the photo, the ‘baffles’ aren’t anything of the sort, just angled slots in the outer wall of the core. A series of large holes, machined in to the inner portion, to leave separate chambers work very well and is what is used in the SAK moderator/suppressor that we can buy in the UK, without a tax stamp for around $40. US suppressor companies seem determine to charge as much as they can for rimfire cans that are far more complex than is needed.

    • Oregon213

      $40 seems like the perfect price for this suppressor.

    • BryanS

      That extra cost comes fromt eh costs in operating in a restricted market, and paying tribute to the kings council on arms…..

  • TheNotoriousIUD

    I know nothing of polymer strength or composition but I wonder if someone (note to the ATF: NOT ME) could 3D print a .22 can?

    • RSG

      That’s essentially what you’re looking at. It can easily be done. They use powdered metal to 3D print, now, too. That’s also possible.

    • Jeff Smith

      I think TFB featured a story about a 3D printed .22 can a month or two ago. I remember reading it somewhere.

    • Gary Kirk

      K, guess my comment is lost in the interwebs.. But, it has been done many times.. There’s even a centerfire can called the brevis, TFB did cover not too long ago..

      • iksnilol

        Brevis ain’t plastic tho.

        So you missed the point of his comment.

        • Gary Kirk

          True, but there have been polymer rimfire cans made as well

          • Gary Kirk

            As to how well they work, or if they’re just a grenade on the end of the barrel.. No idea..

  • doubtingthomas

    Nobody wants the HPA to pass more than me, but it won’t. And I’m sure enough not buying a plastic can from a company that very well may not be around in 5 years. Politically, if we had deregulated cans and the thing cost 40 bucks and came with the 3d print fire to print a replacement core, I’m interested. as it is, for $200, there are plenty of other cans out there.

  • RSG

    When manufacturers start offering stand alone, (center fire rifle calibers), integrally suppressed barrels with an OAL of 16″ for under $600, wake me up. Until then, even if/when the HPA passes, I’m not interested.

  • koolhed

    “The Inland suppressor keeps the decibel level in the low to mid-80s…”

    No. It does not. Stop it!

    • Pete – TFB Writer

      Yeah, I missed this the first go around. Impossible. And I would have called it as such.

  • iksnilol

    Polymer baffles? *facepalm* Oh, the stupidity.

    • BryanS

      How so? Do you know the polymer being used?

      Because we all know this material from the 1960s has not been used in much at all, and still needs to be studied.

      • iksnilol

        They clog up easily, aren’t too durable and not too good with noise suppression.

        At least that’s what I know of suppressors with plastic guts here in Europe.

  • Bradley

    If they ever come off the NFA I think you’ll see a market for cheaper, maybe even disposable to a point suppressors. Particularly for rimfire.

  • LGonDISQUS

    ***NOTE***

    Look at the companies related to this. Inland, MKS Supply – both in Dayton, OH

    This is literally the Hi-Point of suppressors (not that it is a bad thing).

  • LGonDISQUS

    Derp, wrong page.

    Delete.

  • Cymond

    Why? What are the advantages ​compared to the various other rimfire suppressors in the $200 class?

    If price is the main concern, this is a lot more than the Rebel SOS-22.
