Usually this shotgun will sell for $100 -$150 depending on condition and location. The 550B utilizes a single action bar as oppossed to the double action bars that are standard on all Mossberg pump shotguns since sometime in the mid 1980s, I believe. This feature make the older style guns useful, but much less desirable. The 16 gauge is in the same category; useful but much less desirable.
$130-$150 in good condition, great gun
Mossberg or Savage? In any event, $150 if in good shape. sales@countrygunsmith.net
