KWA m4 upgrade(not plural)

[MeticulousAssasin]

if you could do one upgrade for a KWA m4 would you replace the bucking or barrel? Don't say spring that's already going to be done.

Upgrading the barrel may require you to replace the bucking, so you would do well to do both or at least prepare for that possibility.

I would just go ahead and do both, a new systema bucking is only seven dollars.

I would upgrade to a KWA 2G hop up bucking. (http://store.kwausa.com/partsaegkm4serieshopupbucking-3.aspx) I just got mine and it is phenomenal. Also, KWA buckings are slightly thinner than your standard Marui compatible bucking so you are going to have to either purchase KWA specific buckings or try your luck and patience at fitting a Marui bucking without tearing it.

Have you done this with no problem?

Not on a KWA but my CA.

Ah, see KWAs are picky little *****es. They make up for it when it counts though

Yeah, I thought I would I just realized that I may not have to replace the spring (downgrade), but I may be wrong. I was just wondering I was planning on doing both, but I'm not surprised how no one answered the actual question lol.

You've put this in your gun? Does it work? I've got the stock hop-up and the gun is okay, but it's inhibited by it' range.
Let me know how much of an improvement this is.

Also, I put a Prometheus 363 in my KWA M4 and it works well.
