I bought an older Mauser, cheap, that someone had quit "sporterizing" after cutting the barrel back and taking off the original sights. I'm not planning on using this rifle past around 100 yards.

My gunsmith has a set of used Remington 700 sights and some used receiver sights. Both at a reasonable price; $25 for the 700s, $60 for the receiver sights. He believes the reciever sights will give me the potential for considerably more accuracy. IMO he's right but at 100 yards would there be that much difference? I've always thought the 700 had some of the better factory open sights and the rear sight is windage adjustable.
