The comparison you're making is night and day. Not even apples to oranges...night and day. If you don't have sound measuring equipment, your PERCEPTION that it's quieter is not necessarily accurate. MIGHT BE, but not because it's a better suppressor.
The Sandstorm is a .30 cal suppressor. When using a suppressor like this on a 5.56 semi auto, you're going to be disappointed every time. Not only due to the difference in suppressor bore, in relation to the bullet size....but because it's a SHORT barrel, and excess sound is coming out the action during cycling.
The Brevis II is hearing safe on a bolt gun...barely. It's not designed to be as quiet as most and that kind of expectation shouldn't be placed on it.
All suppressors will sound louder on a semi-auto. Even if they suppress well at the muzzle, the perception is different at the shooters ear.
I know, I've got five different cans on five different rifles, both 556 and 7.62 bolt guns and piston gas guns and just ordered two more Brevis IIs for my 556 piston gas guns.
The only rifle I am shooting subsonic is a .300 BlackOut, the 5.56mm and 7.62mm are not subsonic.
