PolarStar Drop-In HPA System for V2 Guns

Recommended Posts

We've been designing a drop-in gas system to replace the traditional V2 gearbox. The primary requirements were high reliability, consistent and adjustable power, minimal recoil and select fire capability all while dropping right into an AEG body. Using a gas power source with electronic control eliminates many of the common weaknesses and points of failure of a traditional AEG (cracked shell, broken bearings, failed tappet plate, sector clip, stripped gears/pistons, etc...).

 

- External HPA

- Electronic Fire Control (Semi, Burst & Auto modes)

- Closed Bolt, NBB

- Two Moving Parts

- FAST Trigger Response

- Independently Adjustable ROF & FPS

- Runs off standard 9v or any airsoft battery >7v.

- Completely Drop-In Installation. No modifications required.

 

Gen 1 prototype worked as planned and even with a restriction in the supply line (didn't have the right fitting for the larger diameter tubing) ROF was still more than acceptable. We're applying a few small adjustments to the Gen 2 prototypes that we're making right now.

 

Gen 2 "upper halves" in progress:

Wow definitely want one of these. I could care less how much it costs. Looks like it will be worth it

I have a few questions:

 

Can it run off of other gases?

Will an M4 still need the standard motor?

Does it take standard nozzles?

Could you fit the regulator of a HPA/CO2 in the pistol grip to make it so you couldn't adjust it during a game without some disassembly?

When will it come out?

Estimated price?

 

And more about HPA rigs instead of the GB itself... Could there be a 'buffer tube' HPA rig with enough gas for 550 rounds at 400FPS w/ .2s?

since we're on the subject of how "bulky" these external hpa rigs can be, let me offer this as a counter point

 

http://www.tippmannparts.com/Ninja-Micro-P...0psi-p/1403.htm

 

looks small enough to fit in a radio pouch

 

I'm just saying/wondering out loud, how many shots do you think we could get?

Even a 4500 PSI tank that small wouldn't last very long, that would last about half of a one hour game.

IMO the best way to go is a 4500 PSI, 45ci peanut tank, Guerilla makes good ones with built-in regulators, pop on a Palmers and some hosing and you have a great dual-reg setup.

 

<AT> Bnoji, have you been able to fit it into any AEG recievers? Does it fit inside of Tokyo Marui or similar MP5 bodies?

This isn't my thread, but I know a lot about HPA/CO2 rigs. I assume it can run off HPA and CO2 for best efficiency, as any other gas will have massive cool-down effect. According to his explanation, it does not require a motor as the tubing goes down and out of the pistol grip. You can't have a regulator inside a pistol grip because the regulator needs to be attached to the CO2/HPA tank.

 

Also, there isn't enough room inside a buffer tube to hold enough gas as well as a regulator. In the classic HPA rigged guns, they tried it- no regulator of course. On a buffer tube filled with green gas you could get *maybe* 30 rounds. With such little space, cool down is inevitable unless you are using HPA, but with HPA you can't get enough rounds out.

 

I am very excited to see how it turns out. I am even more curious to see how fields will deal with external air-rigged guns that can increase or decrease FPS in the turn of a knob.

I think that once this happens, it will either be an honor system (Hey man, don't touch that knob please), or they'll create a "seal" or something over the knob. Something like a tamper seal, so they know you touched it.

 

Edit: This is beyond sweet. I have a "broken" g36 lying around that I'll designate for the release of the V3 drop in kit.

Yup, High Pressure Air, This is awesome. Personally tired of the limitations of the gearbox system and have been interested in classics but coudn't find the motivation to spend the money. This will be perfect. I am hoping that one could make it semi only for DMR applications?

The problem is pressure spikes and change in gas pressure that would require you to turn your knob to stay at the same PSI. Ideally you'd have a dual-reg setup, where one reg limits to the PSI for the field's max FPS and you have another reg for adjustment within that window.

Being an Escort/Classic user myself, this is highly appealing. Please keep us updated as I will pick one instantly.

By any chance did you take some of your motivation from the Bullet Valve system? I'm very impressed.

 

Any idea on release dates or price?

I think he was looking for an estimate in shots... Some people are MUCH more conservative with their shots than others...

 

I think I'll use this GB + PCS +Systema bucking (until P* makes one, then I will see how they compare) + EdGi 6.00 Barrel for my latest project.

If P* makes a bucking, then I will have an all P* internal set up, lol.

This is the sexiest thing I've seen in a long while. Remind me again why gas airsoft guns died out?

During the 90s, the Japanese economy wasnt exactly doing great. It was in the Shitter to be exact. Those classic companies like JAC, Asahi, toytec, etc bit the dust. The TM AEG was also cheaper than the external rig gas guns, so that had a fair bit to do with it as well.

I believe Asahi still does small jobs here and there, Escort seems to be making guns still, but selling them really only in Japan.

Interesting, but I'm not sure it's worth it. I for one know absolutely nothing about any of this system, while I'm comfortable with how a gb works, and I'm sure others feel the same way.

 

While it seems like the benefits are great, it requires a whole new set of equipment - the conversion itself, air, and who knows what else - to work... Maybe a more in depth explanation of how this works, what is needed, etc? I for one would love that :p

Seconded. I've already spent so much becoming so well acquainted with AEGs...

Wait, really? This only has a handful of moving parts, and it's more expensive to manufacture?

We'll have more details on the internal operation when we're closer to the release date.

 

The drop-in box and air rig are the only things needed. It installs the same as a complete gearbox would, but the motor is left out. Nothing else changes. You can re-use all other equipment (mags, body/externals, hopup, barrel) and you can even use your existing airsoft batteries.

Do you have estimates on price? I promise we can handle it :P

I'd believe that there is a lot of specific factors in manufacturing that go into it that would have to be figured out first.

 

Still, something broad like '100-200' or '200-350' would be nice.

I gotta ask, what's the point? (Not being rude... being naive).

 

If it provides the same performance of the AEG (FPS/ROF), then why carry the extra weight of a gas cylinder, etc...?

Granted, other than removing the maintenance of the gears, etc... (if that's the benefit?)

It was designed using an M4 shell as a model. We haven't tested in MP5 bodies yet, but the "core" of the system is compact so we should be able to adapt it to other models.

 

Wow, that thing looks amazing!

but can you detail more about it? I didn't understand exactly what is that. what gas does it use? and why does this need a battery?

generaly, how does this work?

 

Runs on HPA or CO2. It needs a battery for the micro controller and solenoid. We're keeping the internal details private for now.

We can lock out burst and full auto through software for a semi-only rifle.

Its more efficient and consistent. Since there are fewer moving parts and gas is regulated. Some of the most accurate guns in airsoft are run by hpa. More reliable, and can push higher fps/rof without worrying about the stress on parts. Also less complex means more reliable :P and gas guns are just plain cool.

Since a canister is HPA, can I fill it myself with a compressor?

^ The only system that lets you do that, IIRC, is the Nikken Sherman M4, which is about the size and weight of a scuba tank. Speaking of scuba tanks, if you want to use a small tank you can use a scuba tank to fill a small HPA tank from a fill station.

I'm not at all familiar with gas setups. At all. But if it can be more consistent and reliable without a cost increase for consumables (The tank and compressor being a one time investment), I could go for this almost regardless of the cost.

 

Googling for those Nikken tanks sounds like they're rare or out of manufacture.

Not really, a member named "azeus[something]" sells them for $100 shipped and has quite a few models.

And again, like I said, the only air tank capable of filling from a standard air compressor is the Sherman.

All other tanks are filled with larger, more complex machines and air fills are usually free or cheap at scuba or paintball shops. Alternatively you can buy or rent a scuba tank and buy a "fill station" adaptor for HPA tanks for around $50.

...that's what I was afraid of. Some guy is sitting on a pile of them. 100$?... googling shows that's about what a scuba tank goes for, but still... more googling says the higher cost is from the addition of a regulator required for HPA systems vs liquid like C02 as well as the higher pressures... hmmm.

All the paintball fields around me charge you an arm and a leg for refills... and the scuba tank adapter thing doesn't sound too cheap either.

 

Still, if a boneyard JG V2, the tanks and adapter, and this drop in total less than 400$... I dunno.

 

I think straight electricity is still cheaper. These things would have to get 250-300 foot effective range stock for me to really consider.

 

...Hell, I don't suppose these could be made to plug into a scuba tank out of the box, rather than screwing around with two tanks and an adaptor?

Im betting itll be more than that with everything to be honest.

This isnt supposed to be the new cheap way to get a good gun. Its supposed to be simple, effective, and efficient. And the effective range isnt going to be 250-300 feet just from having more consistent shots. I don't think you understand the concept....

 

Mw2 scuba loadout anyone?

Nope.

Everything I quoted makes no sense. Scuba tanks range from $250-500, so IDK what you're thinking, and regulators are required for HPA and CO2, whereas the Sherman system has a built-in regulator.
