Guarder Stainless Steel Double O-Ring Cylinder Head for Airsoft AEG Gearboxes (Type: Version 7)

"Hey guys so used this for my new build (VERSION 2) and it works fantastic!
Here is the parts list, I mostly used guarder for everything except for a few things.
This compression set works great together!
SHS green nozzle
Guarder piston head, sp120 spring, cylinder head, advanced tappet plate, cylinder head
Bolt ported piston

"Fits the Cyma ebr m14 perfectly.

"Perfect seal with a guarder cylinder and RA piston head, also fits perfectly in my jg G3's gearbox.

"This cylinder head is great! It isn't some cheapo "CNC" aluminum, this thing is a brick. The only thing is I had to slightly file out the holes so the shell could close around it. Would happily purchase again.

"I love it! Best piston head for your V.7
My M14 loves it, trust me, I asked him.

"Put this in my Cyma M14 EBR. it is solid and is a a very snug fit in the Guarder chrome cylinder. One thing however..... The hole in the sorbo pad is tapered down so it is a smaller hole. IT WILL LOWER FPS. for me, it was 60 FPS lower. I simply cut the pad so the hole was more like the stock one and I was back to 310 FPS.

"Will NOT work with G&G M14

Have to rate it. The quality stainless is great, just not for my gun
