HPA setup questions

[proffrink]

Good luck. I'm still waiting for those Redline IGLs they said would be in stock 3 weeks ago, heh.

Is that the european QD's or redline US QD's ?

QD's are my favorite subject at the moment =D

[proffrink]

US.

[MrMcG]

Really interested in this

 

 

Want to hpa the vector but no idea how

[proffrink]

Thankfully the Vector is easy, and it's the same answer: CQB Russian valves (the KWA ones). Buy one for each mag, add a small amount of PTFE tape or pneumatic sealant, screw in (only give an extra quarter turn when it feels like it's getting harder to screw in or you'll damage the threads) and you're done.

 

The rig is the issue though. You'll need a tank, regulator and line. A smallish 3500 psi tank would be fine (maybe around 50cl) as you don't have many shots in each magazine. You're looking at maybe in the region of £200 when all said and done, with the regulator being the most expensive thing (even the Ninja LPR is £105). You may need to consider a Scuba tank if you're not close to a paintball or dive shop, or don't have a compressor on the site you attend.

 

The only real obvious downside to an HPA tapped magazine on a GBBR like that is that you do need to swap the QD every time you reload. It maybe adds a few seconds and you can get quite quick at it. A small price for consistent shots and cheap refills I think.

 

I can grab you some links if you like.

OMG is it that easy??

 

I don't need to do any changes to the rifle itself just mod the mags??

 

Links would be fantastic mate thank you

[proffrink]

Just the mags. Obviously HPA is meant to be dry do you need to lube it manually with silicone half way through the day and make sure the mags are not left dry when you finish but yeh.

 

CQB Russian HPA valves for each magazine:

http://www.socomtactical.net/airsoft-accessories/magazines/magazine-accessories-and-speedlo/cqb-russian-hpa-valve-for-kwa-airsoft-gas-magazine.html

Make sure you get the KWA ones and be sure not to overtighten them when installed (again once it goes taught you want to only do one more quarter turn). Also buy some PTFE/Teflon tape to add to the threads before you put them in as this will make the seal more reliable (it's about £2 a roll so don't worry)

 

Beesting (seem to be out of stock on both of these so e-mail them)

Tank:

http://www.beestingairsoft.com/product/guerrilla-air-myth-48ci-483000psi-tank/

Obviously bigger will hold more air but is bulkier. You can opt for 4500psi, but that gets a lot more expensive so I've picked you a 3000psi bottle

 

Regulator:

http://www.beestingairsoft.com/product/ninja-lpr-regulator-with-36-wide-bore-braided-line/

Just an LPR regulator for use with any tanks putting out under 1000 psi (which the one above will as the tank regulator included steps it down to that)

 

Beesting do their own unbranded CQB Russian valves:

http://www.beestingairsoft.com/product/beesting-stainless-steel-hpa-valves-kwaksc/

I'm sure they're great but I don't know of anyone that's used one so maybe do a quick Google

 

Or

 

Rap4 (in stock but slightly more expensive)

Tank:

http://www.rap4uk.com/Cheap-Quality-Paintball-Airsoft-Air-Tank-Guerrilla-p/ms800-1pi_1.htm

 

Regulator:

http://www.rap4uk.com/Ninja-LPR-Regulator-with-36-Wide-bore-braided-lin-p/ninja-lpr36.htm

 

Bonus is they have CQB Russian valves:

http://www.rap4uk.com/CQB-Russian-HPA-Adapter-KWA-brand-p/cqb-russian-kwa.htm

 

I'd suggest shopping around, but that's what you kinda want. A tank of around 50cl or more and a regulator from a decent brand (frankly Ninja and Redline make the best ones). Hose is included with most regulators and has the QD fittings you need. Both Beesting and Rap4 do the different hose lengths. I've found 36" to be good and it's the 'standard' for most players.

[MrMcG]

Just the mags. Obviously HPA is meant to be dry do you need to lube it manually with silicone half way through the day and make sure the mags are not left dry when you finish but yeh.

 

So you need one of these for each magazine. They fit in where the fill valve is:

You sir if I ever meet you I shall buy you beer a plenty

[proffrink]

Heh, you're welcome. Just updated it as I saw a couple of things I may have missed.

[MrMcG]

Fantastic

 

I guess the only thing left to ask is

 

How long would the tank last roughly and how do I fill the thing up

 

Cheers

[LordGeorge]

This is the mystery, I had a go at asking people how long any tank would last and nobody can really answer it.

I would hazard a guess a 48/3500 would easily last you a day if your tapping any gbb mags as you just won't go through enough quick enough.

 

Filling depends on how you go about it, get a scuba tank and use a refill station like the below.

 

http://www.beestingairsoft.com/product/seal-king-hpa-scuba-fill-station-4500psi/

 

If you contact beesting via email, they will most likely offer a discount if you get the kit all together.

They offered the line and fill station free with my reg and tank.

 

If you use the fill station then you only then need to get a scuba tank, have it hydrostatic tested if it's not already in test.

Then finally fill that baby up in the closest diving shop for next to nothing. From what I have heard it's no more than a few quid.

 

If no scuba tank, then just take the small bottle to the dive shop.

 

Prof will be able to answer this thoroughly, I also owe this guy a few beers getting me here now.

 

New toys are coming tomorrow! Yippee

Ace that is what I shall do then

 

Get a decent sized tank and siphon it from that.

 

Thank you for your help as well

 

Be nice to not have to worry about fps and gas problems with temp

 

Wooop

[LordGeorge]

Haha yeah no worries, because of my need I went mental on he tank size just so I never have a issue.

 

I also encountered the cool down and staggering fps fluctuations the weekend using my 416 the first and most likely only time before its gutted.

 

Good luck dude !

Also gives me a cheap way now of getting a scar h gbbr and using hpa on that too woooo

 

Bring on the skirmishes

[LordGeorge]

Haha yes, I am toying with selling my mk17 and getting the gbb variant and Daytona that as well.

I'm starting to dislike AEG's as much I like building the gearboxes. They are too whiney, fragile and common.

 

I do love my scar though.

 

Deffo, love it!

[proffrink]

George has covered it already. Filling is done through the nipple on the top of the tank - it's not the same as Scuba, though basically all dive shops accommodate paintball players as a way to make a little extra money and so will be able to fill your smaller tank too as George says. I would certainly recommend a scuba tank though as a 232 bar one and a fill station adaptor will set you back about £60-100 but is worth it for the convenience of only having to get your tank filled once every 3 games or so. One dive shop near me will do a full 300 bar fill on my 10lt for £4.50, whilst another will charge £12.50. I mean the price is negligible either way compared to green gas, but do shop around for which shop you want to use for your fills as the prices may vary. I'm lucky as there are quite a few around here.

 

Go on eBay and see if you can find anything over 7lt (over 10 is ideal) and a fill station that fits Yoke not DIN (as most 232 bar Scuba tanks are Yoke). I would say to be sure it's been hydro-statically tested first so you know it's airtight, but you could take a risk and buy one that isn't then get it hydrotested at your local dive shop (can cost around £35 or more). I explained more about this in the first page of the thread, so that's maybe worth a read. Tanks generally have a life of 20-25 years (I forget exactly) before they should be binned, so don't overpay for one that's on its last legs.

 

As for how long your tank will last, I just don't know. I've HPA tapped my M870, though I've not used it at a game yet and obviously it's a very different system to any GBBR so I wouldn't be able to tell you. My rough guesstimate would be that it should last you around 25-30 extended magazines with a 50cl/3000psi tank, though again this is worth confirming elsewhere and it a number I've basically pulled out of thin air based upon what I've seen. There's an airsoft HPA Facebook group - try posting there and they might reply. It'll certainly be more than a Polarstar/SMP system, but probably slightly less than the Daytona Gun kits we've been discussing here.

 

Probably all the more reason to get a Scuba tank as you can just throw that in the car and then not have to worry - at most you might need to take 10 minutes to refill it.

 

Regarding your SCAR-H - check the fill valve position. I know I'm boned on my M4 as the fill valves on GHK magazines are up next to the output valve. Good for looking the business (as you can't see them when the mag is inserted), but bad for HPA tapping.
