Inspired by the iconic MP5SD and powered by our proprietary M-Kore™ Technology, this integrally suppressed Ruger® Mark IV™ uses a ported barrel and diffuser system to make supersonic rounds sound like subsonic speed. The result? The quietest rimfire platform you’ll ever shoot. Want a full breakdown?
