USED Ruger Single Six in .22LR. 6.5in barrel. Black front sight blade and drift-adjustable rear sight. Wood grips. The bore looks shiny clean. There are a few small patches of scratches on the barrel and ejector rod cover, and a few tiny dents to the wood grips. Inside the action there appears to be brown grease around cylinder gears and barrel mouth.  This wipes/chips off easily with paper towel or fingernail, and does not affect function.  Overall this firearm is in very good mechanical condition.
