ASG Lonex Ultimate Cylinder Head for Version 2 Airsoft AEG Gearboxes

"Just ordered this to drop in my G&G CM16 Mod 0. Overall seems to have a good build quality, tight fit in the cylinder for a good air seal. The rubber seems very hard so I was concerned about it being to loud and not absorbing enough of the shock. I have only fired a few dozen shots so far but seems fine. I paired it with a Lonex ball bearing mount piston head. 3 stars because I had to modify it to fit my V3 gear box. The holes do not line up with the holes on my gear box, I had to grind some rubber off the front and in the holes to get it to fit. Not too hard with my dreamer but definitely was not right.

"WARNING

Would not work in g&g m4s
Would not work in any ares style gearboxes (elite force m4s) Installation felt great but it was sliyghtly to long and will cause you gearbox to lockup. I installed these on stock guns as well and the gearbox shell flexs a hair and Puts the gears on a slight angle causing them to grind to a halt. Adds a great sound to your gun though. Sounds like a paintball gun really.

"I bought one of these ASG cylinder heads for my CA M4. Great quality product but not perfect.

Good-- Provides great airseal due to the dual Oring base
The cylinder side of this unit has a nice rubber bushing to soften impact from the piston.
The Aluminum build is great for durability and remains fairly lightweight.

Bad--Some people may notice a really tight fitting Nozzle. I called a local shop and had them test fit several other nozzles and everything was really tight fitting.
The pins where the gearbox clamshells had to be widened a bit to fit properly.

All in all, this is a decent product but once again not perfect.

"This is a really nice piece of equipment. It's just as it looks so you don't need to worry about not getting a double o-ring on the head. Now the reason for a two star rating. Only get this if your exact model/brand that it specifies. None of the "similar brands" will work so do not fall prey to that. I did and it is quite annoying.

"Even thou i emailed Evike to make sure they send me one that was exactly as the picture, pointing out the fact that one review said it came without the front rubber part... mine still came without the front rubber part.
The rubber wasn't missing, there was simply no room for the rubber to ever have been there. Just a flat aluminium surface.
