Question about the KWA NS2 system.

Postby EnarahRovaaniik » Thu Jun 14, 2012 4:11 pm

Okay, I'm going to buy a KWA USP that utilizes the NS2 system and I wanted to know if the NS2 system would work well with HFC134a. I wanted to know because it is cheap and reduces FPS a lot. (I'm using the USP for CQB so I want it sub-330 FPS)

If you want to use HFC134a get a Marui, or a Japanese KSC. You may have cycling issues with the USP using HFC134a gas.

Yeah, I knew it was mainly for ABS slide guns, or other Japanese guns. I'll just stick with propane. Also, another question, would propane increase the FPS of a gun as opposed to using green gas? I know they are the same thing, just green gas has lubricants added. I was just wondering though, so if you could tell me that would be great :)

Not sure about the KWA USP, but my KWA M9 (which is also Ns2) works just fine on duster gas. Actually I'm pretty sure all of the gbb pistols I own work fine on duster gas. You may find they cycle slower though.

Okay, thanks for the information. I still have like half a can of duster gas from an old ABS gun that is now broken.
