Special Interest Arms 9mm Bolt Action Rifle

Special Interest Arms (SIA) in Gardnerville, Nevada, specializes in bolt action rifle to pistol caliber conversions. With an emphasis on quiet, SIA is using the Armscor .22 TCM bolt action as a platform for a 9mm rifle/suppressor host. The Novem is available as either a 16″ carbine, a 12″ barrel with a permanently attached cage to avoid National Firearms Act  (NFA) complications, a Short Barreled Rifle (SBR) and an integrally suppressed rifle.

As an owner of a suppressed Ruger 77/357 SBR, I am a big fan of the closed-action pistol caliber carbines as suppressor hosts. Not only are they cheap to shoot, compact and fun, but they are really quiet when paired up with a quality suppressor like one from The Bowers Group. And in the ultimate of specialized suppressed weapons, the Deslile-like integral Novem promises whisper quiet fun.

Pricing on the guns runs the gamut, starting at $750 for a conversion on a customer-supplied gun. (The Armscor rifles can be found for $350-$500 depending on supply and availability). Obviously custom options and integral suppressors will increase the project budget, so your best bet is to contact SIA with any details and requirements.

Oh, I almost forgot, the Novem can also be had in .40S&W and 10mm.

From the Special Interest Arms 9mm Novem Product Page:

  • There has not been a new 9mm bolt action carbine available since the Destroyer Carbine in 9mm Largo was discontinued.
  • We now modify new Armscor® .22 TCM rifles to 9mm Luger using a newly made barrel.
  • Available with a standard 16.5″ barrel, as an SBR, or Integrally Suppressed.
  • The manual bolt action eliminates the unavoidable action noise of any semi-auto firearm.
  • A 1/2-28 threaded muzzle for use with suppressors is standard, with a delete option.
  • Original carbine magazines hold five rounds in 9mm.
  • The Armscor® pistol magazines also interchange for seventeen round capacity in 9mm.
  • Our conversions are lighter than the original 22 TCM unless integrally suppressed.
  • They are a very handy length for vehicle carry or use by youth/ladies with their shorter barrels.
  • The receiver features an 11 mm dovetail for scope mounting.
  • Link to an inexpensive Picatinny rail which has gotten good reviews, DIP Products TCM scope rail.

On a mission to make all of my guns as quiet as possible.

    These look fantastic. I’m slightly surprised they went for 9mm though; wasn’t the original De Lisle originally tested in 9mm before it was decided that 45 ACP was more suitable due to being inherently subsonic?

    • Twilight sparkle

      9 is more common now
      Plus they’re using guns that were originally chambered in 22tcm which has a base that is a lot more like 9mm than 45

      • Ben Loong

        To add to that, the SIA website notes that the original .22 TCM magazines readily accept 9mm cartridges without modification.

        • Jared Vynn

          The magazines could also take 38 super, they were 38 super para18 hi cap mags with modified feed lips from mecgar.

    • iksnilol

      Because back in the day they didn’t make subsonic 9mm, and .45 acp in general was pretty common due to the US.

    • lol

      add to that the 9mm having slightly better all around ballistic drop (especially if you step up to super-sonic rounds)

  • TreeHugR

    In 10mm? Well… I guess I didn’t need to eat the rest of this month.

    • Arandor Thinnorion

      11mm? I’m in.

      • A bearded being from beyond ti

        This one goes to eleven.

        • Arandor Thinnorion

          Glad someone got it. 🙂

  • Peter Nissen

    So finally a Welrod for the 21st century. Thanks for catching Guys!

    • Tom

      The Welrod is a pistol I think you meant DeLisle carbine.

      • iksnilol

        With a hacksaw it’ll be a pistol… at least close enough 😉

      • Fruitbat44

        I was hoping I’d be the first to make the DeLisle comparison . . . nah! 🙂

    • Anomanom

      No, that’s the B&T VP9.

  • thedonn007

    I would rather have a ruger 77/357 as it will have a little more power for deer hunting.

    • Pete – TFB Writer

      It ran here as a picture of the day a few years back. I have a 77/357 & 77/44 story in the works…

      • Swarf

        “Uh oh.”

        — my wallet

  • wetcorps

    Very neat.

  • Renegade

    I’m more interested in your suppressed Ruger. Internally suppressed, or a can? If a can, what can?

    • Pete – TFB Writer

      Search “Grey Ghost” It ran here as a picture of the day a few years back. I have a 77/357 & 77/44 story in the works…

  • Bob

    What is the point of the cage? Longer barrel gives more velocity, yes? So why not just have longer barrel?

    • Ken

      It’s for suppressor use. A longer barrel with a suppressor results in a longer gun, and probably the round no longer being subsonic. A suppressor inside the cage won’t increase the overall length.

    • sundancer32

      you don’t want too much velocity, necessarily, but the cage is to meet overall length requirements so you don’t have an SBR.

  • DanGoodShot

    What? No videos showing us how “quiet” it is?? Cause according to the grand interweb you can hear how quiet a suppressor is on youtube video. Suppressor videos crack me up. I will say there are a very few who do good ones. Very few. The rest seem to fail to realize that suppressed or not, sounds damn near the same.

    • Pete – TFB Writer

      They have a few videos on their site, but they aren’t good enough to imbed.

  • I was just talking to someone yesterday about finding a 9mm bolt gun, so good timing.

  • John

    First post on here after years of lurking. I’ve got one, and it’s awesome. Paired with a Mystic X and some 147 grain 9mm, it’s only a little louder than a 22lr. Also gets great accuracy out to 50 yards with a 1.5-5x32mm scope, but haven’t tried it any further. Lastly the owner of Innovative Arms was responsive and super helpful!

    • Jared Vynn

      Have you tried using para 18 magazines with it?

      • Harbinger1117

        Just got two in this week. Have only cycled the bolt with them. Had a couple of misfeeds during the first few rounds, but it seems like they just needed a few reps to break them in.

        Also have 2 22TCM 17 rounders that work perfectly, but they seem tough to find.

      • Eric S

        The Para Super .38 needs some modding to the feed lips, but otherwise works. I used a Mec Gar version in my rifle and it requires some tweaking.

  • Mmmtacos

    Those models with the cage on the end look like something you might find a Jawa using.

  • SlowJoeCrow

    This makes me want to pursue my idea of a carbine in 7.62 Tokarev. Based on some quick research the cartridge base matches 5.56/.223 and you can use .308 bullets so a .223 action with .308 barrel blank, a chamber reamer and some tinkering with the magazine should do it.

    • Shrike30

      Isn’t that basically .300 BLK without nearly enough powder, once you get done with it?

      • Phil Hsueh

        I don’t know but from what I’ve seen, 7.62 Tokarev is a pretty hot little round. There’s a guy on YouTube who conducts ballistics tests against various helmets, both steel and Kevlar, and of all the pistol rounds he fires at them the Tokarev is the on that manages to consistently punch through almost every helmet. Not only does it penetrate almost every time, it does so in spectacular fashion, usually going clean through front and back leaving some gaping holes. I the only helmet I haven’t seen it punch through is an old PASGT K-pot.

  • Cal.Bar

    FINALLY! Something we can actually GET in CA! (for now)

  • Andrey Martim

    This remind me of the british De Lisle Carbine from the second world war.

  • “Thats my fetish!”

  • Woah, these use the Rock Island 2011 mags. That means you can use the 30 round, 170mm MBX magazines in this.

  • sundancer32

    they do. but quality varies by cost. the cheap ones are terrible for this kind of thing.

  • Joby

    Wouldn’t the 10mm be a Decum and the .40 be a Quadrāgintā?
    I want a Decum

    • Joby

      Not to mention the Triginta Octo Maxime

  • Ryan

    I’d rather a DeLisle.
