WE Scar L - HPA. HELP

Hey guys!

Been AGES since I logged in here.. :p

Anyway, I'm starting up my new rig. I am basing it on the WE Scar L.
First step is to get my HPA-stuff together. I am thinking about just buying nozzles for the magazines at first, and running pressurized air through them.
http://www.airsoftextreme.com/store...e.com/store/index.php?main_page=product_info&cPath=407_437_559&products_id=8347

So, I am running 7 mags (1 in gun, 6 in front) so I need 7 of those. I will have to work on m ymag-changing routine, but that is not a concern.

Anyway, I am thinking of buying a 0,8L 200bar (2900PSI) paintball tank with regulator. What kind of adaptor will I need for the QD HPA connection on my mags?

Another concern of mine, is how much pressure can I run through my mag and gun? I know that Green Gas also has an exponential factor which pressurized air does not have. How do I "compensate" for this?

Also, this is unlubricated air. How often, and in what fashion should I maintain my gun?

A wall of questions, I know.. But all help will be rewarded with a cookie! (you have to pay for P&P's tho)

Also dropping a sub as I've thought about doing the same thing. I have a few HPA and scuba tanks lying around from my paintball days. I want to try something like this myself but I'm not sure how many PSI would be to much for my GBB. I have a KJW 1911 with the red nozzle that is supposed to be able to handle both green gas/propane and co2 cartridges. From some quick research, the pressure of co2 at 85 degrees is around 850 psi (someone correct me if I am wrong), however, I'm not sure if this is the same for the small 12 gram cartridges used in the GBB mags. I've also seen where people mention that propane has a PSI rating of 200 PSI at 85 degrees (big PSI difference between green gas/propane and co2).

If the GBB can handle co2 at 850 psi, then with the adapter you link and these parts, it would seem possible to work with this combination.

I think an adapter like this would be safer because you can regulate the PSI to between 0 and 160 psi, but I'm not sure if that is enough or to much for a GBB.

Hoping someone knows because I'd like to use my HPA tanks if I can.

So after some more research, it would seem that you/I would likely need all three pieces (maybe not the Ninja regulator) After searching through a bunch of forums, it seems that the ideal PSI for GBB is betwen 90 and 120 psi so you/I would need some type of regulator to bring down the 400-800 psi found on traditional HPA tanks to a usable level.

My reasoning for looking at a HPA setup is because I have old tanks from my paintball days and I have heard that GBBP using green gas in the winter time is no all that great. HPA would help during cold days. However, looking at the cost, @ at least $130 it may be more than what I'm willing to spend to play on a few cold days.

Guys!

I just ordered the rifle, an HPA tank and a Ninja Polar-star regulator.
The Polar-star regulator makes 0-160 PSI from the 3000 PSI tank. That should be sufficient enough :)

I have also ordered a nozzle for the OEM magazine, to try out. If all works well, I will be ordering 6 more magazines and 6 more nozzles.


Appreciate the support! Good to be back on the boards :)

Thanks for the input. I believe 850 PSI would blow the magazine to pieces. Its not cylindrical shaped, and would basically explode under the pressure. The 0-160 regulator is a winner.

I guess maintenance will be key in my application, since the air is un-lubricated and dry.

Very true. That is exactly why I am looking into this.
I will NEVER use this during winter, because the lubrication will dry out and the gun will kill itself, but here in Northern Norway there are no climate for GBB guns. Even my pistol suffers on a regular fall or spring day.. As soon as temperatures drops below 15-10 degrees celcius, they are useless.. (Which is all the time up here)

So yeah, pretty excited. Getting my gun this weekend, but I have no clue when the HPA nozzle is coming.

Nice, just a question. How does one fill a HPA tank?

I have two scuba tanks will fill station adapters. I get the scuba tanks filled at a local scuba shop for about 8 bucks. Each scuba tank will only fill to about 3000 psi but that is usually enough to get about 15 to 20 usable fills on my HPA tank. You can take your HPA tank to the local scuba shop, but they would charge you the same to fill the small HPA tank and the larger scuba tank. Two tanks would normally allow 6 plays to play paintball all day.

On my paintaball gun, a 4500PSI fill on 68u tank would get me about 1200 or so shots.

Ok, so if I bring a HPA tank to a Paintball field they will fill my tank? Great! Now I am even more intrested...

That is also an issue of mine. The local Paintball place just shut down, so I need a scuba tank as well.. Maybe getting a used one this weekend.

The rifle arrives tomorrow.

Have you considered a Daytona Gun / TNK Mk16 SCAR? It is based off of the WE platform, and it would be a lot more cost effective, usable, and more enjoyable, while converting your rifle to HPA. It would also have even more kick than the original GBB platform, and uses AEG mags.

Here's a link:

This guy actually has one if you want to see it in use, but its in Russian:

Their website: http://www.tnkguns.com/Airsoft.htmlr

They don't have the Mk16 SCAR listed on their site yet, but if you email them (the email link is at the bottom of their website) they will gladly make one for you. It will take some time though.

Hope I was of some help.

I have evaluated it, yes.

However, I found that a traditional GBB platform would be a little more interesting for me.
I mean, sure - Daytona gun seems great, but there's something about the GBB rig I find better.

First off, the open-bolt mechanism. Second, the 30 rounds magazines. I also have the impression that the Daytona is more of a polar star with blowback - I like the whole mechanism of the GBB.

Extremely good suggestion, and I will buy one if these HPA-adapters for the magazines does not work-



In other news, I have got myself the HPA tank, the Polar Star regulator and the WE Scar-L. Also, I have bought a second-hand scuba tank.

Now, I'm just waiting for the filling station and the HPA-adapter.
If the HPA-adapter seems to work well, I will buy 6 more mags and adapters. If it turns out to be a PITA, I will buy a Daytona gun kit instead. :)
