We need a manufacturer to make an HPA M700 that has the gas bottle inbuilt into the hollow stock with the pressure valve inbuilt somewhere so it is visible and the air tubing to be hidden through the stock. Then the mag would not have the big tube sticking out of it and it would mean that you would not have to carry a bottle on your back. You also would not be so tied to the gun.
I know you can put the CO2 gas in the stock but it would be good to have a larger gas capacity so you do not have to change CO2 canisters so often. So a stock size HPA bottle inside.

Its a good thought. The only issue is that time is money in the manufacturing world, sadly enough. It's 100% possible, but if KJW spent that much time working on a single rifle, researching and building, they would dig themselves a nice pit, requiring many sales to break even.
To add to your idea, the older Tanaka long magazines had twin gas chambers, like pictured here:



If some machining master and intellectual genius put his mind to it, he could put a CO2 cartridge in one chamber, connect the two chambers, and put a regulator in the other chamber, and boom. What I had in my stock + tubes etc, this guy now has in his magazine, with perfect aesthetics. Sadly, this man is fictional; however, I am sure that someone could do it.

I had designed something to that extent. One problem is it is a complete redesign on the system.

To go off what 1tonne said, as far as putting an HPA tank in the stock, while possible if you used a very small tank, it is highly unlikely. HPA tanks, NOT CO2, need to be recertified every X# of years. The US, EU, and many other countries, require it to not only protect shops, but owners as well. Due to the fact that HPA bottles can rupture and explode, rocket off, or a few other things.

We could do what TM did with the m870, but we would still have the same problem as the m870. The gas tanks apparently, in hot weather, expand causing the tank to stick inside the stock. I do not know the extent of the damage that it causes. Additionally if the stock were a tank running HPA, you would eventually need to replace the stock. If the rifle fails to be popular then you are going to be up the creek with out a paddle.

If it were designed to run off CO2 then it would be easier, still need sufficient expansion room so you do not freeze up the valve and reg, not that it would happen in a sniper rifle, but you would want to limit the number of points of possible failure. Which would mean hard-lining the connections through out the system, which would increase the end cost as those connections are expensive. Unless you ran it on a removable chassis that screws into place. Mind you that is what I would have done.

End of the day, it would be amazingly expensive. Sorry to be Mr. Buzzkillington there.

It's the sad truth:

It'd be cool, and very useful, however it is simply not possible for a manufacturer.
Think of it like this: Heckler and Koch removed their trademark licensing with KWA pistols, but kept them on the lower end companies like the things you see at Sporting goods stores. Why? High end players love trademarks! As for sporting goods, why the hell would a kid care about HK trades on a clear-plastic gun? Truth is, that doesn't get H&K the money they need from the higher end models, therefore they revoked the license.

What does that mean here? If KJW were to do such a thing, the only people who would value such a system would be we higher-end snipers. That kid who doesn't know anything about sniping doesn't value said system, and would opt for the cheaper model. The issue here is that the high end snipers are sadly a rare breed. Us alone would not bring the needed income to KJW.

Sad truth, I know, but thats why there are people in this world like Careful, Dobey, and other machinists and geniuses that know what they are doing, and how to do it. Thats why we have a special word… Custom Or even better, one-of-a-kind

(And with that comes money, which is where I lose experience…)

Custom builds, absolutely doable. From a large mass production stand point, probably never going to happen. Unless someone comes up with a tank that can hold 4500 psi that is the size of a co2 quick change system, that is relatively inexpensive.

Now if we are talking about lets say using one of these, http://www.amazon.com/JT-90gram-CO2-Tank-Prefilled/dp/B005QIK966
then sure, I am sure someone could build a rifle to work with these. Mind you the tanks above are not refillable.

Im the guy from Youtube btw bobcat ;) I still can´t decide which KJW m700 i should buy, Police or Takedown Edition?

Ive read bad and good things about both, I like the idea of opening my gun in very easy mode, but I also like the hop up adjustment on the rail of the police version...

Need help :( both 239€

You could, not saying you can't, but I think the biggest tank you can fit on those is a 13/3000. should be more then enough. But not every one likes m4 stocks, also there is only like 2 that even do that. Sure you could mod a stock or 2 but then that is getting into the customizing, and blows the whole "out of box" thing.

This is how I had mine rigged up before I sold it. It'd be pretty difficult to fit a regulator and CO2 canister into a single magazine. It would certainly look nothing like a real magazine by the time someone was done engineering it to all fit together.

I sure hope someone is able to do it, I just doubt it as of right now. Did you ever manage to r-hop your M700? Haven't been on the forums for awhile.

Police version hands down. The hopup system on the takedown is a major hassle and will cause you plenty of accuracy issues.
