"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 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.
