KWA Full Metal 40rd Magazine for KWA KZ61 VZ-61 Skorpion Airsoft GBB SMG

"Bought 5 of them. Contrary to what some people say, they were to all able to shoot all 40 bbs and *more*. Just make sure to fill them for at least 15 seconds. As the reviewer before me stated, 20 seconds is a safer bet. My only gripe (more of an aesthetic con) is that it comes with these orange warning stickers on them and it's impossible to peal them off cleanly. The residue is very hard to get off.

"THESE MAGS 100% HOLD ENOUGH GAS.

I see sooo many people complain about how these mags don't hold enough gas. That is a bunch of malarkey. They, in fact, can hold enough gas for well over 40 rounds.

The issue is KWA makes garbage fill valves. They don't fill very fast at all. So you HAVE to fill them for ~20 FULL seconds to get enough gas into them.

Another issue is if the mags are warmer than the gas you are filling it with, the mag will reach a pressure equilibrium well before enough gas can flow into the magazine. Just fill the mag a bit and empty it a few times to cool down the mag, then it will draw in gas for the full 20 seconds or so.

DO THIS AND YOU WILL NEVER RUN OUT OF GAS MID-GAME.

"It definitely holds enough gas as long as you make sure it's actually full. I usually start the match with it when using as a primary and reload using the smaller ones as I go.
Pros: Heavy and sturdy. 40ish rounds great for almost 2 seconds of full auto to completely empty the magazine and have enough gas left for you to blow out the magazine when you are done.

Cons: Heavy and bulky. I think it shifts the weight a little forward taking away from the good balance the gun already has. The spring follower is very strong and the loading catch is sturdy but sensitive to allow for a quick release, however if you trip it after a few BBs (around 10) it will have enough inertia to shoot them all out the top and crack the bottom of the mag lips leaving it still usable but with a slight depression that you cracked your new mag.

Does what I want it too but because of it's size it's a little finicky.

"Let me get straight to the point. This mag is built very well, everything on it is high quality. The only con i found in it is that the mag does not hold enough gas to shoot out all the bbs. I may have got a faulty one, I dont know. It always runs out of gas leaving me with 5 to 10 rounds in the mag. Not to big of a deal but is worth mentioning.

Pros:
-Amazing build quality
-good bb capacity

Cons:
-Doesn't seem to hold enough gas to shoot out the last 5-10 bbs.
