What he said. Don't go with the "package" as set up for sale commercially. Go with your own "package" or combo of chosen rifle & scope.
First, are you willing to go used?
If not then then only way you can get a good rifle new, AND a decent scope and rings, for under $400 is to go with a Mossberg 100 ATR or Rossi single shot, or NEF single shot. Used, you could add Savage or Stephen. You need to spend at least $190-$200 for a scope (or a minimum of $160 for a Nikon Prostaff), plus some *quality* rings & bases, not the crap that comes on the factory combo. Are you ok with plastic stock? If so, then I'd go new Mossberg 100 ATR, or used Stephens 200 or used Savage 110/111, or used Mossberg 4x4, throw on Leupold bases, Leupold rings, and a scope in the form of a Leupold Rifleman, Burris FF2, Simmons Aetec master series, Nikon Prostaff, Sightron S2, Nikon Buckmaster, or Leupold VX1, and you're in bidness. If you want a wood stock, same scope & rings/base, but add a new Rossi single shot and new NEF Handi-rifle to the mix of choices.
