Duration: 1:42

This video from Ruger provides a technical deep dive into the sound reduction capabilities of their Silent-SR suppressor. It presents measured decibel levels across various Ruger firearms (.22 LR pistols and rifles, .22 WMR, and .17 HMR) using different ammunition types. The data highlights the significant reduction in sound signature and also demonstrates how environmental factors can influence perceived noise levels.

Quick Summary

The Ruger Silent-SR suppressor significantly reduces firearm noise, achieving levels as low as 113.3 dB with subsonic .22 LR on a rifle. It also performs effectively with .22 WMR (125.3 dB) and .17 HMR (123.5 dB). Environmental factors like shooting under cover versus in an open field can alter measured decibel levels.
