"Great spring with the right equipment with it such as piston & cylinder. I need time to break mine in my JG BAR10. It chronoed around 570.

"Works great. A lot harder to pull the bolt back, but the FPS increase is worth it. I went from 410 FPS with the stock spring, to 510 FPS. Get the sear set and the spring guide to make sure you don't destroy your gun.
