While browsing Gunbroker the other day I accidently pressed the buy now button and bought a 870 home defense shotgun with an extended magazine.(truth). At this point the seller will not let me out of the deal ( I am not done trying). If am am required to purchase this gun can you folks help me trick it out in a moderatly priced way. I may do this and then re-list the gun. Who knows I may even keep it if I can get it to the sufficient level of ninjatude.
