"I don't know if it's the bore-up (doubtful) or just the quality of the parts in achieving airseal, but I've installed this in two different gearboxes with no tricks like teflon or permatex, no extra o-rings or anything, and with an AIM torque gearset, a fresh m120 and 407mm 6.03 inner barrel it consistency pulls 420-430 fps where before these gearboxes were struggling to reach 360.

"The Kit is great and has a perfect air seal once it is lubricated. I didn't see much of an FPS gain, only 5-10 fps, but it is much more consistant. Overall it is a really good set and makes it a little quieter as well, this could be a pro or a con.

"Great kit except the air nozzle. It would come loose off my tapet plate when fired. I would give this set a 5 star if it came with a cnc or aluminum air nozzle. Besides the air nozzle the rest of the kit is great!!

"The quality of this set is great except for the air nozzle, it is cheap. I installed this on my King Arms Galil Mar and in test firing it the air nozzle broke at the groves where it seats on the tappet plate. Plan on upgrading your air nozzle when buying this kit.

"Great part, but the picture shows a cylinder head that does not have a ridge on the top (Why I ordered it). You see, the ridge on the top does not fit the version 3 gearboxes, at least not CYMA. To my dismay, the head has the ridge on the top, despite what the picture shows. I am getting tired of Evike's mislabeling and advertising/pictures. The upgrade parts seem to be the only thing they can't get right, like a different company is running it.
