I have here a ruger sr 556 in superb condition. Shot very little, it has literally sat in the back of the safe for the last five years. This was ruger high end rifle back in the day. This is not the cheaper "E" model. This is a piston ar with adjustable gas piston.  It's the more desirable model with the round handguard vs the heavier one picatinny rail. I would say no more than 300 rounds thru it. Will come with a 30 round pmag,ruger flip up sights,scorpion grip & magpul front grip. Looking to trade for a tactical 308 bolt action like a ruger rpr in 308. Will consider other manufacturers....second choice a mini 14 with folding stock or a tactical 30-30. I have multiple ar's so don't really need this. Thanks
