Comically bad FPS ~E90 aeg

It chronoed 120 FPS. I think an LPEG shoots higher. I added a 363mm barrel.

If you did not open the gearbox, the air leak is likely in one of a few places.

The hop-up bucking may be incorrectly installed on the barrel or inside the hop-up unit. This is the most likely problem.

It may also be that the barrel and bucking aren't seated against the gearbox correctly.

I opened the gearbox to see why there was teflon tape all over the cylinder head. I took the tape off and it still fit snugly. I think most stock nozzles are horrible sh*t also. Since the GB is so user friendly I'm going to check for compression which I didn't do the first time. I have a feeling it's all to with the air nozzle. Being Junk in the first place and not seating against the hop up and cylinder head.

-Air nozzle, seems fine. Don't know how to test.
-Piston-cylinder compression, excellent.
-Nozzle-hop up compression, don't know how to test.
