I'm thinking about putting one on a 7.5" 5.56 pistol.
Good use-case for these? I don't want to fsck with NFA cost, hassle & being on their list.
I've not tried them on any short barrels like that, but the physics are the same.
That being said, I've shot an SBR that was suppressed quite a bit. It had a 12" barrel. .223 caliber.
Even with the suppressor, that SBR was about as loud as my 18" .223 was unsuppressed.
