Picked up a Brand NEW Ruger mini 14 tactical yesterday and was going to shoot it today but I noticed rust in the action all along the bolt. The top of the action where the magazine engages has a little also. Is this normal for a new gun? Haven't experienced this before and I'm going to attempt to clean it tomorrow. It looks like the gun has been stored for a while, not at my gun dealer but at the distributor. I just didn't expect rust on a gun I paid good money for. I did glance at it at the dealer but didn't notice it until I was wiping it down today. What would you do, clean it or take it back?
