I decided to pick up a 2011 Kaos Pump w/ single trigger. I was wondering what upgrades or modifications you'd recommend for it.

[Zepulkinator]

Regulator, On/Off, a barrel that has interchangeable backs or one that is a .684 or less and a clamping feedneck.

Besides that, I don't' think that there is much more you can upgrade on those.

But, by the time you do all that, you could have bought a better pump. The good thing is, the barrel, regulator and on/off should be transferable to your next pump marker

Spyder main spring and a new Magna valve (Spyder as well?) will stop the farting...

As was said above, reg, on/off and feedneck...and a single trigger frame and your done.

I would only suggest a new barrel and maybe a new clamping feedneck (depending on if your loader fits). On/offs are not necessary, and if your regulator works there is no point in replacing it. For the barrel, I would suggest a Lurker eigenbarrel.

Well I have a freak kit, and I believe it comes with a NDZ feedneck along with the stock feedneck. I might have a check-it on/off too.

Did the 2011 model reduce the farting any?
