First things first:

I do prefer the Palmer's regulator. I've been able to achieve ± 2-3 PSI per shot, and that by itself is great. No need for a dual regulator. Palmer's Regulator is a superior regulator for CO2 since it is designed to handle the case of unwanted liquid CO2 in the chamber. It handles great, and just cause its old doesn't mean its worse...

And as for ovionepr

Have you tried testing the seal? Start there. How new is your regulator? It may need to be broken in. What does the PSI deviation look like?

Yeahp what he said ^

by blowing down the barrel and making sure that there isn't a leak.

Another popular way for M700 users is putting it in a bucket of water... when pressurized there should be no air bubbles. Fire the gun, again no air bubbles.

Yeah sure

So he's got this reg: Low Pressure Female Stabilizer

which take paintball tank threads

then this adapter: CCI 12 gram Quick Change adapter - Airsoft Gas & Air - Airsoft

which uses CO2 12g canisters

Or at least thats what I have, but I'm sure that he's got the same

should work fine

Tanaka does have a ball bearing for a nub

No experience with Tanaka chambers

Exactly why I question sellers when they say their M700 has a "custom TDC"...

The down side with that route is that it can hinder bipod use in certain cases and angles.

Since the connectors are external, I would recommend using a barbed fitting and clamp rather than your standard push connect. Push connect fittings are annoying sometimes because if the tube is pushed too far in one direction, the o ring seal opens a little allowing for leaks... (massive leaks). When the CO2 is situated inside the stock, the stock housing keeps the tubing in place to prevent this, but since you want it outside, you should stick to barbs.

I personally think barb fittings hold the tube better, since the friction fit is much stronger than the push connect's barb hold. You can also get barb fitting to QD fittings from McMaster, this makes things easy.

The upside is that the regulator is always pointing up when firing straight, so the chances of liquid CO2 events are diminished.

Some tips:

Usually its easier for a new player to buy a JG BAR-10 to see if they like the role of the sniper- its not for everybody.

If you have your heart set on the KJW:

I have no knowledge of the Begadi thing, I use Palmers and its the best regulator I've seen for CO2 application, and it fits inside the stock.

The threaded adapter you bought can be used if it is machined, like you did.

I would have stuck it in a lathe to machine it down to size, then bored out the inner diameter to a slightly larger diameter so that the barrel doesn't touch it. The barrel spacers keep the barrel in line, the threaded adapter does nothing.

I like your "******* engineering" though! I know most people would have just returned the part.
I always knew my SCAR adapter wasn't the best, since it was a friction fit, made for those without tools *like me*...

bobcat · Mar 31, 2015

Eh, I only came up with that idea once you mentioned that the machining had to be perfect. If it isn't perfect, then I think my route would have been more forgiving, but if it is perfect then there should be an issue and act like a spacer.

//Yep... thats everything you need. Some other things I would buy:

Mini Gauge, 0- 300 PSI - Gauges - Air Fittings - Industrial

/*
This is because the gauge it comes with is 1.5", and the stock's largest width is maybe around 1.05". The gauge I linked is a 1", the one I use.

Make sure you have a stiff, sharp knife for that macroline... I used a hacksaw once...
*/

Now I personally think that "package deals" are a bad thing. This is because it limits you to what you can and cannot do. I'm not necessarily a fan of Palmer's fittings and tubing. Their regulator and M700 adapter is great for our applications, but not much else.

I personally would have chosen to go to McMaster and found strong-flexible-<200PSI tubing. Then some QD fittings that use barbed fittings and not the push connects. They have a stronger hold and allow for a better bend radius.

tl;dr
What you have is fine, but there are different, better ways.

QD-Tube fitting McMaster-Carr

QD-Pipe fitting McMaster-Carr

Tube-Regulator McMaster-Carr

Pressure Gauge 0-200 PSI McMaster-Carr

And then either

McMaster-Carr
^This is stronger and braided with nylon fabric, doesn't bend as much

McMaster-Carr
^This is not protected with nylon but can bend more

And of course the regulator from Palmers

I feel like I answered this question already

bobcat · Jun 12, 2015

yeah, those are the "originals" so to speak. They used to be around $30, but the scarcity drove the price up. They're discontinued and I tried to get mine directly from King Arms. I spent $112 on the chamber alone... After 3 months and a bunch of conversations with a rep, I decided to cancel and refund the order because something told me that when customer service said, "The factory will send them to us next week", one a week to me, I felt like they were trying to kindly tell me that the part ain't coming...

You don't need the part if you don't have a Tanaka (aka, you own a KJW)

I used co2 for a while, I still use it from time to time.
HPA is generally better; it rarely suffers from pressure drop. The downside is refilling the tank is difficult for me since a station is 2 hours away, and that you are attached to the gun.
The line never bothered me, and neither did the tank.

I use co2 when I run out of HPA, and when I want to run super light (aka no tank)
...oh yeah, I only run "super light" in the summer time for a reason...

CO2 still drops pressure a little over temperature. Hot weather loves CO2...

bobcat · Jul 2, 2015

The standard length (650mm) is insane for HPA. You want power? Get the Lonex 750mm barrel and turn up to 200 PSI. Much fun. It is also quieter than a short barrel, since you don't need as much pressure to propell the projectile to the wanted velocity. Yeah, increased length, but your choice.

bobcat · Jul 4, 2015

I personally don't give in to the whole wide bore thing, because the air would never be perfectly distributed 360 degrees around the bb. This is just because the bb never sits perfectly in the middle.

I still used the stock barrel for quite a while since my intervention with Angel Custom and the 6.01 barrel I was using... I had better performance from the stock barrel. Not sure if it was because of the bore or the barrel quality. I'm sure a higher quality 6.10 would be better than the stock one for sure.

Everyone gives KJ hate for their massive barrel, but hey, maybe they are on to something. Everything has a reason, right?

I went back to an AirsoftGI 6.01 after I cut my barrel shorter... No change what so ever.

Hey Simon

I know I've answered this question several times through both PM and on this thread.

I shouldn't have to quote the original post, but I know its there. In the top theres a section labeled "CO2 in the Stock" or something. It covers everything. I think its worth a read...
