Hard to answer that without more information. Ned to know which model you have, what sort of stock or grips it has or other accessories, how old it is, how much use it has seen, and what kind of overall shape it is in.
Well the mini 14 comes in stainless steel. That is made by Ruger. There is also a Ruger 22 cal. stainless steel rifle.
50-600 USD or so
50-250 or so
I like the stainless steel Ruger mini 14. You did not say what cal. or rifle or pistol.
You would have to define what accurate means to you- but in general, Ruger makes good, accurate firearms.
100-350 USD
