I have a chance to buy an older Ruger M77, tang safety, Ruger sights and red recoil pad in 7x57 Mauser. Excellent condition has 2 small dins on the rear stock that ya really have to look for to find. The fella that has it wants $850.00 for it. I see they are selling for this on Gunbroker. Is this a good buy, should I hold out to see if he'll drop the price, what do ya'll think????
