This last week, we spent some more hands-on time with the SilencerCo Salvo 12 – and to say we were impressed would be an understatement.
We pulled out the sound meter and tested the 12″ configuration with multiple types of shot, from #8 down to #4 – and will be posting videos on our tests over the coming days. All the testing so far has been done on a Benelli M4 shotgun.
It’s amazing how different it is to suppress a semi-auto shotgun vs a semi-auto rifle!
When suppressing a semi-auto rifle (like an AR15), it’s common to have the sound at the ear be just as loud or louder than the sound at the muzzle. The primary reason for this is the sound that’s forced back through the bolt as it cycles – and that’s why bolt action rifles generally suppress better.
With that background, I was expecting the Benelli M4 to have a similar effect; but, it turns out the numbers at the ear were significantly quieter than the muzzle numbers. Although we have a lot more testing to do, I suspect the excellent suppression at the ear is a result of the slower cycle speeds on a shotgun.
Unfortunately, the differences we heard didn’t come across very well in the videos; but, we did metering at both the muzzle and the ear – and the numbers are amazing. We’re upgrading our sound equipment to better capture the differences on this suppressor for future videos.
To sum it up, we were seeing numbers at the ear in the mid-to-high 120dB range! This is absolutely amazing, and it was well within the comfortable range.
Once again, stay tuned for several videos of the 12″ configuration over the next few days. I can’t wait to get it out to test some of the shorter configurations!
