Ruger Mini-14 , .223 cal. semi-auto carbine. Serial #185-87626.  Very good condition.  A very interesting Ruger that was used by Six Flags, Los Angeles in their Batman Stage Show at Magic Mountain, CA.  A certificate from Stembridge Gun Rentals is included explaining the carbine was used in a "stunt shooter on tower" scene.  Fully operating and NOT an inert prop gun.   18" barrel has a very good bore and has been counter bored and threaded for a blank adapter.  Walnut stock has a  few hits and dings. Missing rear sight. Good tight action.   Blue  finish is very good with some light wear and a few scratches.  Unmarked magazine.  A very cool Mini 14 with an unique history.   Well-documented.
