You are bidding on a rare vintage Smart Parts 4500psi adjustable tank regulator and 68ci Carbon Fiber air system for paintball.  It comes with the matching rail as well.  No gauge or macroline fitting is included but everything else is there.  Please see photos for details.  Regulator may need to be service since it's been in storage for quite some time.  Physically it's in great shape as shown but air tank is overdue.  Perfect for any collector of vintage paintball products.  Any questions, please email me.  Bid with confidence and check out my other auctions for more paintball products.  Auction is for U.S. Only.
