Ruger Announces Silent-SR ISB Integrally Suppressed Barrel

Continuing our march towards “normalizing” silencers within the gun industry, rimfire powerhouse Ruger is manufacturing the Silent-SR ISB – an integrally suppressed barrel assembly for the 10/22 and Charger platforms. Although I will avoid Hearing Protection Act (HPA) hopes-and-dreams discussions, the fact that a major firearms company is building such unique suppressors hopefully signifies an important milestone in broader NFA ownership.

The Silent-SR ISB features a two-tiered baffle and shroud system that gives the whole assembly a lot of room for trapped gas and expansion. The separate chamber also allows for for an easily accessible takedown screw for baffle cleaning and maintenance – a must for suppressed rimfire guns.

Although the barrel length is slightly longer than 10 inches, the shroud itself is more than 16 inches long, negating the need for an additional stamp for a short barreled rifle (SBR) should you decide to use the ISB on a 10/22 with a shoulder stock.

If Ruger’s 113 dB levels hold true, this integral suppressor will be a huge hit amongst rimfire fans.

Ruger Introduces the ISB – An Integrally Suppressed Barrel for the 10/22 Takedown

Sturm, Ruger & Co., Inc. (NYSE: RGR) proudly introduces the Silent-SR® ISB for the 10/22 Takedown® platform. The ISB, or Integrally Suppressed Barrel, is an exciting addition to the Ruger® Silent-SR family that delivers quiet and accurate performance in a compact and truly user-serviceable package.

Known for its unrelenting reliability, durability and accuracy, the 10/22 Takedown rifle is the ideal platform for an integral suppressor. The Silent-SR ISB quickly and easily assembles to any Ruger 10/22 Takedown or 22 Charger™ Takedown, and features an induction-hardened breech with cold hammer-forged barrel that provide easy takedown and accurate return-to-zero – the same elements that have made the 10/22 Takedown an instant classic worthy of its heritage.

Reducing sound pressure levels of .22 LR to an average of 113.2 dB with standard velocity ammunition, a 10/22 Takedown rifle equipped with the Silent-SR ISB is as quiet as a bolt-action rifle with a thread-on silencer. Its compact, 16.12″ barrel length makes the Silent-SR ISB easy to handle, and the relatively long barrel of the Silent-SR ISB (compared to other integral suppressors) means the bullet generates energy near that of a 16″ gun for consistent, accurate and effective performance on target. The pushed-cone baffle geometry has been stretched to utilize the volume under the barrel maximizing suppression of the gunshot without disturbing the travel of the bullet.

Disassembly for cleaning is as simple as separating the barrel from your firearm and loosening the Silent-SR ISB’s single assembly screw using the included 5/32″ hex key tool. Once loose, pull the screw to remove all six 17-4 stainless steel baffles, spacer and front cap free of the sleeve for cleaning. The sealed baffles keep the fouling away from the serialized sleeve, yet easily come apart even after thousands of rounds. Finished with Cerakote, the Silent-SR ISB is engineered and built for a lifetime of hard use without clogged ports, seized components or loss of suppression that often plague other integrally suppressed rimfire barrels.

Suppressed firearms help to preserve our hearing, make verbal communication on the range easier and make shooting more fun. Paired with the Ruger 10/22 Takedown, the Silent-SR ISB makes the perfect training, plinking and small-game hunting platform.

    While I’m not a fan of the two-piece front stock on the Ruger takedown rimfires, I really like the look of the suppressor itself.

    • Ruger Shooter

      What in the world is wrong with a two piece stock? I have a SS Take Down, threaded, flash suppressor, fiber optic sights, laser and IR 3-9x scope. Fits in bag with scope on. The extra barrel pocket in the backpack would accommodate a suppressor barrel nicely.

  • PK

    The look, the materials, the design, the press sheet… Ruger, you’re doing this right top to bottom, even if that ends up sounding like a middle of the road .22lr can. If it sounds great, you’ll sell a ton.

    I’ve got NFA 10/22s already or I’d be placing an order for one of these already. I’m still thinking about it, just to encourage this sort of product!

    • JumpIf NotZero

      Hammer forged 22 barrel, take down, integral suppressor that is actually quieter than muzzle cans, takes down with a common tool, 17-4PH baffles, light enough…

      Agreed, if Ruger does one thing better than anyone else in the firearm industry it’s read the market.

      • PK

        Indeed – and I hope they next read the desire for an integral .22lr pistol. A factory, integrally silenced MkIV would hit the spot quite nicely in stainless.

      • Giolli Joker

        Damn… Ruger even manages to get you writing a positive comment… chapeu to them!

    • nova3930

      Oh yeah. I’m totally in for one. Give me an excuse to buy a 10/22 takedown

      • PK

        I looked again, and for $629 MSRP I’m in. I didn’t even notice the price at first!

        I bet they’ll be $550 or in that neighborhood from the right dealer, too.

  • Jeff Smith

    Hey, Colt and every other firearms company – take notice and make things people actually want.

    This looks fantastic. Does Ruger make a takedown version of the American rimfire rifles? If you could put this on a bolt action, I imagine it would be even better.

    • AndyHasky

      nope, also the barrel is different from the 10/22 anyways. Very few people but aftermarket barrels on their Americans.

      • JumpIf NotZero

        Right; the bolt action guns need to specifically headspace which is not a feature of the take down.

        Ruger COULD make an American TakeDown with a tiny floating bolt head though and that could use this and the other takedown barrels.

        • AndyHasky

          Ruger will probably announce a takedown american when sales slip a certain amount on regular americans….

  • Ratcraft

    Wish it had a threaded barrel for a suppressor.

    • Pete – TFB Writer

      Wait. What? Hoping sarcasm.

      • B-Sabre

        Dude, I heard you like suppressors, so I got you a suppressor for your suppressor!

        • Pete – TFB Writer

          Lol. Well played

      • Edeco

        It would move the front bore-hole further from the shooter’s ears. Or one could ninj it up with a blast deflector.

        Mostly pointless, but the prophecy must be fulfilled. It’s destiny.

    • TheNotoriousIUD

      People dont think ahead anymore.

    • Scott Tuttle

      I need to get my ears threaded cause that comment blew my mind.

    • RealitiCzech

      Plus it should be in 10mm.

  • TheNotoriousIUD

    This product is on point.

  • Scott Wagner

    Ruger built a gun so popular it essentially became a system….and then they come out with this that doesn’t fit any of the aftermarket stocks out there. Unless there are some MASSIVE benefits to going to this barrel shape, it looks to me like they made a mistake.

    • iksnilol

      Comrade, hacksaw.

      Solves all problems 🙂

    • Once Magpul sees the pre-orders for this magnificent creature, do you really think it’ll be all that long before they have a range of accessories available for it?

  • iksnilol

    Looks like an OU shotgun. Neat.

    • PK

      You know, that’s true! It has that look, which is clever for added internal volume without being in line of sight or ruining the overall look.

      • I’ve been wondering when someone was going to release an integrally suppressed rifle with an underslung suppressor and the holes drilled on the underside of the barrel, specifically so it wouldn’t bork the sight plane on top of the receiver.

    • Giolli Joker

      That would look great on the Charger.

  • Xtorin O’hern

    the only thing ruger could have done better was make a version that fits the magpul takedown stock

      • Mystick

        Thank you!

        • Pete – TFB Writer

          Sorry, I didn’t realize the Type on the product sheet would be so small.

          • Mystick

            Ah, now that you pointed it out, I see it now 😉 My bad…

  • publius1969

    Anyone know when this will be released?

    • Ruger Shooter

      When Ruger announces something it is released. However, demand can quickly outpace supply, even with a healthy number available to start with.

  • YZAS

    Ruger is going to sell 1,000,001 of these (one being to me of course!)

  • Daaaaannnnnggggg.

    I didn’t think Ruger was going to be able to top the MkIV for Pure Sexy, but it’s nice to be wrong sometimes.

  • GearHead

    Magpul you’d better be working on a new hiker takedown forend for this!

  • Harry’s Holsters

    That MSRP isn’t bad either!

  • Whiskey7Actual

    Did anyone see the wicked witch pelosi having an aneurysm over the possibility of suppressor laws being changed priceless!

  • Ruger Shooter

    Seems as though Ruger & Henry are almost the only manufactures to actually listen to it’s customers.

  • Kelly Harbeson

    Order one now. If the Hearing Protection Act passes there will be a year waiting list

  • BeoBear

    Any word on if these will come in a finish to match stainless TD’s? I’d love to have one for my TD but does it require a mismatch appearance or waiting for a an unknown time for a stainless finish version?

    I know, buy it and have it cerakoted but $$$ isn’t exactly growing on any of my trees.

  • Green tip

    I realize it’s ‘probably’ drilled/tapped for an optic, etc., but it needs irons (BUIS) of some sort…
