Relax - I remember that picture of your gun from Arnie's. - I love that Prime Limcat Slide!

Romulus - Nice find. You know how I love them long dust covers As far as green gas and WA is concern, it works, just not that well. The mags can barely hold a full load of propane, they start leaking and blow out top rubber, they just aren't designed to handle the pressure like TM can out of the box.
Anyways, I do look forward to seeing you build it.

Henatro - I had a chance to build a Prokiller just like yours and found the same problem. What kinda of FPS you getting out of yours?

Eckhorn - At least it's clean.

Lol Eckhorn was referring to my xcelerator which is in "the cleaner's" hands

the4thpower3 - The last time I chronoed with with stock internals, loose bbu and an improper 150% spring from a 5" tm I was putting out about 315fps with propane at room temperature. I'll test it again once its fixed up.

I remember seeing this a while back when I first discovered western arms. It was like a huge inspiration...

I am curious as to what upgrades are useful in a gun like this. Is the lightweight CP leaf spring worth getting?

Essentials:

-floating valve
-piston -
-extended firing pin
-mainspring (find something similiar to Sheriff's mainspring cap/spring combo)
-recoil spring
-high power valve (diff from high flow valve),

High power/output valve has ONE large slot on the top of the valve that channels more air readily to the BBU. Flow to the BBU is more stable...acts like a venturi

High flow valves have larger openings radially and moreso increases blowback not necessarily power. Air flow to the BBU is turbulent and not efficient

You will get most of your power from the piston upgrade (however, a DBC 6.01 might get you even more)

The floating valve stabilizes air flow through the nozzle and into the hop up chamber/barrel.

As with any gun, you have to upgrade everything as a system. For instance, you should not install a stiffer mainspring, if you haven't upgraded the firing pin.

nice to have:
-metal hop up chamber
-DBC 6.01
-reinforced nozzle
-nozzle return spring (not a necessity as the gun will work fine w/o one)
-CP/SD/PGC BBU
-disconnector
-hammer sear
-leaf spring
-other steel bits for the hammer assembly
-anything else available

Thanks for all the info. I need to put an HK order together and pick up the essentials. I also just got a second WA 6" SVI (this one's a hybrid so I can steal the upper from it and have a hybrid gun) which I need to take pictures of. I think that I'll swap some parts around to build the best gun that I can and then sell the other one. I still don't quite know what I want though so I'll have to try out some different looks.

How hard is it to swap out the firing pin? Do you have to take the whole hammer mechanism apart or is there a short cut (I really like the look of the system since it actually uses a firing pin rather than a valve knocker).

very easy to remove the firing pin...use something pointy that's roughly the same size or smaller than the firing pin..push the firing pin all the way through the plate..lift up on the plate SLOWLY..the firing pin will shoot out if you're not careful!!! So as you're sliding the plate up n off, have your finger or something else backing up the pin from firing out. DONE...

if you can't find a Magna 6" Hybrid slide, I can machine a slot out of that PGC slide you got from me.

Perfect, I was hoping that it was a quick swap.

The other gun I got actually has a metal STI 6" Hybrid slide on it so I'm good in that department. I really like how the PGC 6" slide looks too though so I'm not sure which to use in the long term.

try to get a extended firing pin, it will be much better with the CP one way valve

Rom, i have the stainless firing pin holder...
