Lonex Compression Upgrade Set w/ Mushroom Type Piston Head for Airsoft AEG Rifles (Model: MP5)

"It was almost impossible for me to get the cylinder head into the cylinder. Took lots of lube and a set of channel lock pliers and the O-rings got a little roughed up. After that though I perfect air seal.

"Installed in my jg civilian aug and in my echo 1 civilian aug, works like a charm, cylinder head was a super tight fit, and the nozzle that came with it was an eighth of an inch shorter than the original so I couldn't use it, it also doesn't have o rings, aka pretty useless. Other than that worth the buy
