Suppressed Vs. Unsuppressed Muzzle Blast


SWR have published some interesting videos to their Youtube channel recently. In their latest video they use a balloon, a high-speed video camera and their new SWR Specwar 762 suppressor to show the difference in muzzle blast between a suppressed and unsuppressed rifle.

    So, did they try it without a 90 degree brake? Of course the break will create muzzle blast, it’s supposed to do that to reduce felt recoil. I’m curious if no muzzle attachment has the same effect?

      agreed. this clip needs 3 videos: no device, muzzle brake, and suppressor.

      Yeah, this does make me more curious of other types of breaks compared to not having one.

      There is another way to decrease the muzzle blast. Use a longer barrel than 16.25″..

      They’re also not mentioning that the rounds themselves have different loads. Full powered supersonic ammunition vs. lower powered subsonic.

    i’d like to see the balloon next to A2 flash hider, when the gun goes off…
    of course a .308 with a brake blasts as hell….

    Props to SWR for the comparison videos on their channel, all dB results appear to be published even when a competing can from another brand is quieter.
