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

"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 👍

"Not much to say other than it works. It’s well made. The overall construction is super solid. The interior surface is very smooth. It seals incredibly well with Lonex cylinder heads and piston heads. And I haven’t had any former issues in any gun that I’ve put them in. Only “con” is that the ribs on the outside tend to get pretty dirty. But that’s just me nitpicking. I highly recommend this product.

"Installed this today and have some first impressions.

Pros:
Smooth interior surface unlike other stainless steel cylinders. You do not(and should not because it is a coated surface) need to polish it

Has a heat-sync on the outside

Cons:
None as far as I can see unless you do want to polish your cylinders

"the material is very strong but it came full of waste used to turn it black.
the inner diameter is slightly smaller than the standard, causing friction when pulling the piston.
I'm going to test it on other piston heads because my ICS MK18 DD didn't fit correctly
