ProWin M4 GBB magazines for: WA, G&P and Inokatsu, Release date: Mid June 2009 Rating Options

[KWP]

They say it can adjust to different sizes to fit the WA, G&P, Ino and the Prime lower receiver.

Stats, videos and pics on their website: http://www.prowin-technical.com

One distinctive feature is the enhanced valve lock with roller:

I don't see why the 20 rounder has to be limited.

I thought these had been cancelled? Or was it another manufacturer?

[hitmanNo2]

Same manufacturer, but the technical problem they had has been resolved.

It'll have to do something pretty special or be pretty cheap to beat the competition. The GHK magazines and original WA magazine I use have all worked pretty well so far, and the GHK magazines are just so cheap to buy.

[hitmanNo2]

Well there is their CO2 magazine which will hopefully be good.

no way these will be cheap as the are CNC, but hopefully that allows for a better seal. If you watch the videos it also shows very little cool down which is a HUGE plus. Also having the roller pre-installed is excellent as it makes for one less thing to buy. I know I will be picking one up as soon as I finish my magna system build.

Just wanted to point out one inaccuracy in the ProWin data sheet: they say that only the ProWin mags can use Magpul Ranger Plates. This is inaccurate. I have one on my GHK mag.

Liking those short 20 rounders, wondered who would be the first to release those

[xerxes]

If they get their act together and knock out reliable CO2 magazines that'll operate in the 328-370FPS range on 0.2g ammunition and run off powerlets, I'll take twelve. (IMG:style_emoticons/default/smile.gif)

That would be impossible. CO2 operates at such a high pressure that just operating the recoil system would result in higher FPS then that in the WA system at least.

[Firefly0]

Co2 is regulated inside the magazine, you wouldn't want 800 psi for any GBB.

[MCXL]

"Regulated" doesn't mean Regulated. Something on that small a scale is not going to be able too consistently control gas flow. A more accurate term for a in mag regulator would be a restrictor. Many people run 2 regulators on external setups, I doubt that they can fit even one of those regulator systems into a WA/WE mag.

[renegadecow]

They've already made CO2 mags for the WE, can't see why they can't do the same for the WA system. WETTI said their mags are regulated. As to how these are regulated by means of a dual chamber or just a pinhole to restrict flow, they won't say. But the mags are made to shoot at 350~500fps depending on what nozzle you have on the carrier which means the mags in themselves perform equally to regular gas mags only that they are usable in the cold.

[MCXL]

IIRC they are pinhole. The WE system regulates gas flow to the barrel in a very different manner then the WA inside the bolt system, so its kinda an odd comparison.

[xerxes]

Then all you do is fit an adjustable bolt in the WA / G&P / Ino, and make sure the mags put out as little gas as possible! Shocker eh?

[MCXL]

Wont work consistently. I know of many fields that have banned internal Co2 Airsoft guns. Simply because it may chrono at 400 and then hit the field and shoot a shot at 600 or 700 FPS.

[shinhk]

if it were really that simple...INO would have made those co2 mags ages ago.

[MCXL]

Good point. (IMG:style_emoticons/default/wink.gif)

In my eyes there are two things that every after market company worth their salt should be working on:
-Co2 Mags
-20rd Mags

There is currently a huge demand for both of these things, so I really don't know why ProWin put time and money into re-doing what had been do. Sure, as shinhk said, it will not be easy to make Co2 mags, but once they get it right they will get all of of their hard work back in the form of lots of $$$$$$$$$.
