I'm a new member and I Just bought my first rifle the savage axis in .223 I have a redfield revenge accu ranger varmit 4-12x-42 along with weaver base and Burris 1" rings gonna be my coyote gun. My question is should I plan on doing the extractor right away or should I wait til it acts up? I'm decent mechanic wise never really tore into a rifle is this a hard job or take your time and it's easy?
