The USH shines as a long range acurate slug gun, kinda oposite of what you are looking for.
When You say "brush Gun", "real thick" I say smooth bore Moss 500 or Rem 870, mount a red dot on top of the reciever. for $200 total this is a good, cheap, deadly brush gun, and to boot you are shoting $3.00 box slugs, not $13.00.
