Hi, just bought my first rifle! Ruger mini 14 188 series. Bought used at a local pawn shop. Been looking at minis for awhile and couldn't 'pull the trigger' to buy a new one for $900 so I got this. Want a 580 but good luck finding one used! Where do I start with mods/accessories? Definitely would like to get a scope, not really expensive as for mainly target shooting and varmints. Should I used factory rings or put a rail on it? Barrel stabilizer? On BTW its wood stock with ss barrel. Thanks in advance!
