BUR #22152 has been approved by @nonamethanks.
Currently because there are no posts that mention the name/logo of this arms manufacturer or characters personifying the company, I think this tag can be rendered useless. People can simply search for Barrett_* for certain models, rifle or anti-materiel rifle instead.
Also, is it better deprecate it as well?
For the same reason as far as I remembered, the tag "Beretta" was once nuked by a BUR made by an admin months ago (cannot find it anymore).
