ZCI entry level complete gearbox. Comes with a non-vented cylinder and a non-linear M120 spring. The gearbox might be ok to drop into a DMR however for anything else you will need to change the cylinder and spring at the very least. I recommend a re-shim and re-grease. Defaintely only for seasoned Airsofter techs who know what they're doing. It's great value and the gearbox has some nice features like radi corners and wire-channeling.
