"will this make a .223 lawn mower engine quieter" O_o

  To clarify, 1/2"x28 is the standard thread pitch used on most .22 and 9mm caliber firearms for muzzle attachments. In most cases it's a flash hider or a recoil compensator, but suppressors can attach in the same way. Also, this one is an example of an "ambiguously legal" listing. The thing is, after all, an actual oil filter, albeit a poorly made one. Owning it alongside with a firearm it can attach to would likely constitute constructive possession of an unregistered NFA item, but that's buyer's problem. Although I would imagine the seller can still be sued if it can be proven that they knew how most of their customers are using them (which is evident from reviews), and intentionally designed them for that purpose. But, well, good luck suing a noname Chinese merchant.
