Another Mini-14 question

[azleite]

Hi Folk's, I've had a hankering for a couple of guns for awhile. Both are definitely "wants" & not needs. A Ruger Charger (Done deal) strictly for fun. And a Mini 14. My LGS has a used Mini tactical w/ the black stock & AR birdcage. Mfg 2009 w/a ser# prefix of 580. They have the gun w/one factory 20 rd. mag only for $550 + tax. Condition shows some handling wear + where a scope was mounted at one time. Mostly could use a good cleaning. My question is whether or not this was a good series w/ decent accuracy- I'm not expecting a target gun. And is the price reasonable. I already have an AR. Also would a wood factory stock just swap out with the plastic one? Thank's for any help-Dave
