Guarder Enhanced Cylinder Set for Airsoft AEG Gearboxes
(Model: P90)

"Fantastic air compression. Gives more consistent shots.

"Installed this in my G&P M4, and let me tell you that this is so different from stock parts..

Pros:
Air compression for cylinder and nozzle is out of this world
Easy to install if you know your way around the gearbox
Fairly priced
Fat and juicy o-rings
Sturdy piston and piston head
The finish on the cylinder! Wow!

Cons:
Nozzle coming out from the cylinder head is a little weaker than expected, be really careful/gentle if you are intending to do a cylinder head damper mod!

"got this for a DMR set up. I installed these into my Dboys scar (i got another air nozzle but the stock one for m4s is really good.

pros
AMAZING compression
decent bundle price
guarder
reliable
very sturdy (hold a m135 at about 20 RPS)

cons
none at all
