BAAL CNC Stainless Steel Bore Up Cylinder Head for Version 2 Series Airsoft AEG

"This is a really good cylinder head, take note this is a bore up kit so this is used for your dmr and spr kind of set-ups. One review talks about it not fitting but that's because it needs to be used with other bore up parts. If you want to build a dmr then then get this please it has amazing compression and no air leaks.

"As this other review said, this is too big for a normal cylinder. It's for a BORE UP cyclinder that's why it's labeled as bore up.
NOT COMPATIBLE WITH NORMAL CYLINDERS

"Horable product. Was way to big for ver 2 gearbox don't get it's a wast of money
