I found a new Maverick 12 gauge for sale at my favorite local gunshops $160.50 with tax. It has 1 barrel and a plastic stock it looks like a good start. I would like to add a pistol grip,barrel shroud,side saddle,fore grip & pump handle,picatinney rail with Red or Green Dot, a cruiser lenghth barrel and a slug barrel. Am I saving $$$ by buying and upgrading a bare bones gun? I need someone not so emotionally envolved to be more objective voice.
