I finally disassembled my gun and this is what I found a smaller and shorter crooked spring than the Vorteck spring that I replaced it with.a damaged piston seal a very thick washer for pre load and round tube inside the piston.Its no wonder I was having low FPS numbers.I polished the piston and air compression chamber.The vorteck spring had at least a good 2 inchs outside the gun where the old spring was barely even with the end of the gun ugh This was a re-manufactured gun.New number 15.89 JSB 775 fps
