Is shooting thru an unattached sound-deadening device an ATF device?

[Bang]

Scenario: shooting from a bench, rifle supported, free-standing "box" with sound absorbing qualities with a hole allowing the barrel slight entry and an exit hole for the projectile.

Would that be a "silencer" (silencer is a BATFE term for a suppressor) governed by the BATFE rules? Or does their definition specify attachment to the gun?

In the minds of clear thinking humans being that said deadening device isn't attached you're good to go 🤔 but in the minds of subhuman leftist thinking pencil pushing communist Neanderthals you'll be locked away for 20+ years without your beloved friend 🐕 sparky

I've seen some ranges where you lie down in front of a pipe with sound deadening foam to shoot. I would think that would be fine, but you never know with the scumbags at AFT.

Some public ranges in KY have pipes you shoot through.

I bet if he insulated those tires you'd hardly hear it.
