If you're talking about the inner barrel, it looks like it's using its own barrel design, albeit fairly simple: you'd have to mod an aeg barrel yourself though, chopping the hop-up portion off and adding grooves for circlips (snap rings).

As for the value of doing so, I've considered it but given that it's a shotgun I find it TOO accurate already. I want more spread to my BB pattern, nor more accuracy. There's no point in having 5 BBs hit within a few CMs of each other.

As for hopup, the 8mm DOES have hopup, the 6mm does not. I've been looking at ways to add a fixed hopup (like oldschool springers had). I actually want to do one of those "half assed" hopups that were very inconsistent between shots, hopefully it would force a larger pattern by introducing some randomness to each BBs flight pattern.

I need to test it with lighter weight BBs (.12s) though, haven't found in Marui ones in Canada and don't want to order BBs from HK without having other stuff in the order (expensive shipping due to weight, the bag of BBs is like $3).

Update, found some new information we can now avoid drilling/tapping

[Long_Bong]

You could get some 6 mm 0.12 bb at Walmart I believe.

Any picture available of the final mods?

Hi,

Started playing with the M500,

What about drilling the screw on the bag of the reservoir and use this kit:

Get the piping to come out by the grip (pistol grip) and have the reservoir hidden in a battery sling?

Would this mod make sense?

[Long_Bong]

Ok, here is what I planning:

Refering to this:

http://www.airsoftcanada.com/tech/Ma...g%20M500_1.gif

Drill in part 25, get a CO2 rig to connect thru that part and use the M500 with CO2.

[Long_Bong]

Nevermind the drilling,

What about using this to store a small co2 canister in the stock with the wiring going to the valve?

I don't feel there's much point to doing all that work, just to have a small tank on the side. You might as well just carry a slim propane tank in your gear for all the extra gas that solution would provide.

The main downside to this mod is that you'll run out of loaded bb's long before you run out of gas. (That's mainly for the 8mm version; the 6mm ver. holds a lot more rounds but you see my point) And these guns are no treat to reload in the field.

Another thing you should consider; these CO2 and HPA tanks put out anywhere from 1000 to 4000 psi. The shotgun only requires around 100 to 200 psi to operate. The higher you go, the more dangerous you are to others, and beyond that the gun will not hold back the gas. The main seal around the front of the firing pin will burst and at times, hurl itself down the barrel to freedom (I know from experience :P ). You'll end up having to buy a pressure regulator (~$120) which will take up more room on the stock.

I'll take some pics of my setup and you can get some ideas and decide if it's worth it.

UPDATE:

I decided to drill out and tap the high pressure release valve since it wasn't going to be used here. Eventually went with a 90 degree press fit connector.
Body was drilled and tapped to 1/8NPT, a common plumbing and paintball thread. Feeds into a Macro line (the worst thing about this project.)
And if I decide to go back to propane I just thread in a blank, and it's good to go.


Ran the "too-damn-stiff" Macro line along the stock.


The money shot. HPA tank, and Palmers Persuit Low Pressure Regulator (stabilizer actually.. I think). 0-700 psi fully adjustable. Only need a few turns to get my 200 psi.


Remote line with slide check. I originally hoped to go from tank to gun with this, but found it would require me mounting the stabilizer on the gun itself.


The whole getup, with tank in bag. Not horrendous, but that god damn Macro line is too stiff and will make gaming this thing even less fun than it already appears.


In the end, I should have walked away from this one. I still have to tweak it to find the right pressure so it won't hurt, but to be honest, I don't see myself using it at game. I'd much rather use it with propane in a skirmish for shits and giggles and then back to aeg's or pistols. I don't regret buying the gear though, because pneumatics are awesome (geek out!), and I can use this basic rig for other things.

Anyways, enough blathering; at best it's an interesting toy, at worst a warning not to throw good money after.. er.. not as good money.

If you're reading this, you're obviously not put out by external air rigs so I just want to ask if you know of some drop in mechboxes for aegs that can run off this air source. I'm going to do some searching, but if you know where to get something like that, please let me in on it. Cheers..

So, if I got it right, the main issue with your set up is the fact that the air hose linking the M500 to the tank is too stiff? Changing it for a more flexible hose could be possible I would assume?

[Long_Bong]

Did some research,

What bout using this type of macro line:

5/32 Outer Diameter 3/32 Inner Diameter poly tube. Used on QEVs. This is the softer stuff... 300 psi max

The shotgun would run at 200 psi, so pressure would not be an issue...

The shopping list for this project would be:

5/32 OD 3/32 ID poly tube
1/8 NPT to 5/32 Slip Fit 90 Elbow (Converts 1/8 NPT to 5/32 tube with a 90 degree swivel elbow.)
1/8 NPT to 5/32 Slip fit tube - Straight (Adapts a 1/8 NPT hole to 5/32 slip fit tubing)
Airsoft Inline Stabilizer Remote Hose Kit (http://www.palmer-pursuit.com/cart/i...fcc4ji6j2mbik5)

Would this make sense?

The setup I have, which doesn't involve drilling/tapping uses a 4mm house so it's alot thinner and not as stiff, plus I can use it with GBBs

My regulator works for classics so I can run it at about 110psi which is what propane runs at usually (or so I was told).

Also Murdoch, it looks like you got something else attached to your tank.

My regulator attaches directly onto the HPA tank so its not that bulky especially cause I got a pouch for it in the back of my RAV vest.

[Long_Bong]

What would be a precise shopping list of what you would use on a M500 to make it work with CO2?

Also, anyone know what time of valve is use on the M500? (standard GBB valve??)

Marushin and KSC use the same one.

So in the list I sent you it is the F-TYPE 2 valve.

Just email Tirador.

Thanks,

But how do you connect to the CO2 tank?
Anything out there close to the:

KWC CO2 Gas Fix Pressure Supplier Pack

With 12 gram co2 mini tank, anyway to avoid using a ''expensive'' regulator?

[aZn_triXta07]

KWC CO2 Doesn't work

You need a regulator.

It's pointless to use 12g CO2s

Just stick with propane.
