The ISB features best-in-class materials and an advanced design, which means a lighter more compact size and top-tier sound reduction. No joke, the average sound decibel that comes out of this ISB is right around 113.2 dB. That's just about as loud as a mouse or fairy fart. So, take a listen to this week's Buy or Bust as Jim, Trav and Mrs. Bunny give two thumbs up to Ruger and their all-new Silent SR. Check it out, you'll absolutely dig it.
