Ruger Offers Integrally Suppressed Barrel for 10/22 Platform

We bet you’ve never seen anything quite like this before — a rimfire rifle with an integrally suppressed barrel assembly. Ruger offers this technology with its Silent-SR ISB, a multi-baffle integrally suppressed barrel (ISB) for Ruger 10/22 takedown models. This system reduces sound levels to an average of 113.2 dB with standard velocity ammunition. That’s very impressive — consider that an unsuppressed .22 LR firearm can produce noise levels as high as 140 dB with standard velocity ammunition. That’s well above the threshold where irreversible hearing damage begins. (Source: NC Silencers).

Available only as an aftermarket accessory and subject to an NFA tax stamp, the ISB is an integrally suppressed replacement barrel designed for use with any of the company’s numerous takedown-capable rimfire models (the 10/22 Takedown and 10/22 Takedown Lite rifles and the 22 Charger Takedown pistol) MSRP for the Silent-SR ISB is $629.00.

How well does the ISB work? The system was tested by American Rifleman in May 2019. The testers noted that sound reduction varied considerably with ammo types. Also: “Point-of-impact shift between the factory barrel and the ISB was considerable … so plan for some re-zeroing when switching between the two”.

Even if you are not interested in a suppressed rimfire rifle (or live in a state where suppressors are forbidden) we think you’ll be interested in Ruger’s technology. Here’s what Ruger says about its ISB (Integrally Suppressed Barrel) for the 10/22 Take-down:

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.

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. 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.
