I am selling a PDI Vacuum Piston and Vacuum Spring Guide for the Tokyo Marui VSR 10. Both parts are brand new and in their original factory wrapping. These parts are also compatible with the JG BAR 10 series and other exact clones of the TM VSR 10. The asking price is $59 with free shipping. I am also willing to meet in person if you live close by ( I live in Chandler, Ray and Kyrene).
Please feel free to ask any questions regarding these parts!
Thanks for looking!
