Zero Recoil Operating System

Zero will for any of the Kaos series markers but to actually utilize its benefits you need a regulator. Just as stated above.

I think I picked up a Kaos 3 given the color scheme. It is the tan and brown. This is my first stacked tube blowback since my fleet of Spyders in the early 2000's.

The Azodin Kaos-D I used to have came with one. You could effectively change valve spring tension from the front of the gun , as if you were swapping out valve springs, say with a maddman kit. You might need to put a reg on this gun to get the full benefits.

ANS website says it is compatible with Blitz and Kaos markers. I have a Zenith, zero system works pretty well.

Just picked up a Kaos off of Ebay. Is leaking down the barrel and won't re-cock due to a bent valve spring. While shopping for replacement springs I stumbled upon the Zero. Most of the research I have done has led me to believe this was marketed on the higher end Zenith, but has anyone used it on any of the other markers? I am assuming that they are all machined the same.
