I plan on selling one of my rifles but dont really know what to ask for it. I bought it in 2004 brand new straight from Ruger for $550. Its a ruger M77 MarkII, all weather,.223, has a brand newredfield 4x16x44mm scope, and a brand new harris bipod. The gun has no scratches, wear marks, or any sign of rust. It only has about 150 rounds through it. Any help on the estimate of its worth would be greatly appreciated. thanks
