Lonex Stainless Steel Ribbed Cylinder for Airsoft AEG
(Type: Type 0)

"works great. insane compression and efficiency. you do have to use a mallet to get the lonex cylinder head in it. overall recommend.

"This is my second review of these cylinders. My opinion hasn’t changed; they’re great. Very strong and smooth. I’d be surprised if one failed. I’ve compared these to a lot of other stock and aftermarket cylinders and it might just be me but these feel like they have a tighter interior tolerance than most; I always get a great seal. However, I moved away from using Lonex heads with these cylinders as the tolerance is too tight. To the point that getting them on requires removing an o-ring and and beating it in. Seal is good, but it’s too much of a hassle. I’ve been using rocket airsoft cylinder heads with these recently and they work beautifully. They still seal great but can actually be installed/removed with a minimal amount of force. Overall still great cylinders, but tolerance between parts might be something to keep in mind.

"Best cylinder ever purchased, super tight fit with shs cylinder head. Was getting 380 to 390 fps with .28's.
Had to swap from m120 to m110 and got 340 to 350 fps with .28s

This was also paired with shs Swiss cheese piston and lonex pom expanding piston head 👍
