Tokyo Marui PSG-1 With Box, Manual, and Magazines (Airsoft Collectors Item)

I'm looking to sell a rare Tokyo Marui PSG-1 With Box, Manual, and 4 Magazines. I purchased this a while ago and had it upgraded but never used it. I still have the box and manual. Still functioning but due to its age I would check internals before running it hard. I would not recommend running a high-end LiPo battery in it due to its age. the magazines in question are two high capacity mags and two mid cap mags.
