i good trick to see where grinding is needed, is to take the compleatly striped down lower and put some playdoh inside.
press the gearbox into the lower and then once removed, you should see where the contact points are.

Sounds exspensive but fun.Do G&P have C7 trade marks?.
I am building my PRO-win gun from scratch and it has been very reasonably priced, I did buy a used CASV off of ASC but the complete build with over sized and ambi furniture, is just under $900.

I have never seen a G&P with C7 markings (doesn't mean they don't exsist)Voodoo had the C7 body and couldn't get it to work. If you really want a C7 get a G&P with out trades and have it custom engraved, but now you are looking at a bit more $$$

Use a coloured crayon, something like white or a bright colour that shows up easy. It will rub off or transfer to the gearbox during fitting, and you will still be able to see the contact points.

It's going to be nowhere near as messy as play-doh.

Just under $900? Is that including mags & batteries? Mine's priced at $1200 with 10 mags and a batt, but not the optics I'm wanting. What's your parts list like?

Now out of production, this Lamborghini of gearboxes features:
- CNC Made 7mm Gearbox with Bearing set for M4/M16 Series

- Spring Release Switch for longer spring life
- Compatible with most after-market parts

Package Includes:

* Custom modified Prometheus Hard Piston to fit gearbox
* PGC Hop-Packing (Hard, recommend for M130+ springs)
* PGC Aluminum Nozzle (Brand New)
* PGC Cylinder Head (Brand New)

Modifications required for some parts and metal body, installation should be performed by experts.

Parts required to complete the installation:
- Gear set
- Anti-Reversal Latch
- Motor
- Piston Head
- Cylinder
- Hop Up rubber (I don't recommend using the one it comes with)
- Pin to stabilize cylinder head (or a shim will need to be created to keep the cylinder head from sitting too far forward)
The kit comes with everything else you need, although there are always better aftermarket parts available for items like the spring guide.
Used, excellent condition. With packaging
Price: $280
Qty: 1

if i were you, id go with the 8mm version, the 7mm one has all sorts of problems, one being that the piston sits too far forward, and will strip the back tooth.

and then theres feeding issues, so i would go with the 8mm one, i did, and couldn't be happier.

Sorry, no longer for sale.

As for the problems with it, the cylinder head has to be fixed in place. Pro Win gives instructions on how to fix it in place, but doesn't give any indication of what distance, nor do they supply the pin for it. The cylinder head will also need to have a groove machined in to it to accept the fixing pin.

As for feeding issues... I never had any. As long as you don't use the included hop up rubber, there shouldn't be any problems.

I want a gearbox that just like... pops open on the side. And I can just throw in a new piston or gear set on the field. Or, in fact, I want a gun that I can just throw a new gearbox into. Just like a door opens, and I put a new gearbox in. Thats what I want.

yes just under $900, but that doesn't include mags. I already had a battery and optics.
I have:
1 KA CASV 10.5"
1 G&P Zombie Killa M4 Body
1 Crane Stock
1 Mad Bull Tactical Ambi-dextrus Charging Handle
1 KA Sniper Trigger Guard
1 Systema Trigger Assembly
1 Deep Fire Piston
1 Set of Systema gears
1 Systema Magnum Motor
1 KA SPR Grip
1 KA Set of SPR Flip up Sights
1 KA Ambi-dextrus Mag Release
1 Guarder Hop-up
1 Guarder Anti-reversal latch
1 Set KA Locking body Pins
1 Sling attachment thingys that goes between body and buffer tube.
1 Mad Bull M120 Spring
1 8mm Pro-Win
1 Madbull 383mm 6.03 inner Barrel

I did buy a second hand stock and front end, but I have building this one for a 6 months so I would only pick up parts when I noticed a deal.

I am currently building another Pro-Win M4 and it look as tho it will be around $1100. But I have purchased a new KA Gemtech Talon kit and that pushed the price up a lot.

My gun kicks ass with the PRO-WIN (8mm) it shoots 415 FPS .20s with a M120 at 18 rpm with a 9.6 3300 mah

thats a little impractical, why would you need to do that??? with a pro-win you can change the piston, or spring in about 5 minutes..... or a PTW which you can drop a new cylinder in, in 30 seconds.

you can it's called an M4 kind of. Undo the body pins, undo you grip and motor pull old mech box, drop new one in.

I was looking around for M16A2 upper&lower receivers blank,I did realize
this was going to be a pricey build.Are there any good quality M16 stocks
rear.I did a tactical prone position and tweaked the seam,no biggy,little
bit of glue,fixed.When you say the bodys need sanding down inside,how
much are you removing?.:cool:

i had to shim my upper part back, it was to far forward

but thats with the 8mm, i was guessing it was the same way for the 7mm one

psh but ive got to take out the pin above the trigger, take off the stock. I want my gearboxes to be like mags. Just throw them in and out. That would be awesome. Like... Stripped piston? Gears not cycling? No compression? Switch blown? Whatever, throw a new one in and keep destroying. Thatd be great. I wouldnt have to worry about breaking internals. I could have the most insane set up ever, and just carry around a bunch of gearboxes in pouches. Id pay good money to anyone who can make it happen.
