WE-Tech V3 30 Round Steel Magazine for WE Open Bolt M4 Airsoft Gas Blowback Series Rifles (Version: Green Gas / Black)

"Very impressed with my WE M4. I have about 2000 rounds through three of these mags. One was leaky when new, but stopped leaking when the seals got some silicone oil on them. Otherwise, I have not had any issues, other than screws and other threaded parts coming use, but that's pretty normal. Use threadlocker on screws and the nozzle if they come loose, and it should solve the problem. I ordered 6 more mags.

"Great Mag if you have a WE M4 or SCAR (I doubt it!) Works great even in cold weather and average FPS is about 20 FPS higher than green gas.

"A good choice for the WE GBBR user. They feed beautifully in my WE L85A2. I prefer these to the green gas/propane mags because green gas is expensive (and not locally available for me) and propane smells pretty bad. Co2 is available to me, doesn't smell, and works better in the cold.

As Bobby C. mentioned, these have a tendency for the valve to stick after 20-25 rounds on full auto. I'm not certain as to why they do this, but they work flawlessly on semi, provided you space your shots out a bit (a second or two should do). GBBRs work best on semi and in my opinion, should always be used on semi, so I am not upset about this.

Pros:
No stinky propane or expensive green gas.
Better cold-weather performance than propane/green gas.
Co2 is widely available.
Doesn't seem to leak as much as the green gas mags do.
Higher velocities (if the gun isn't shooting hot enough for you already).
30 round capacity is highly realistic and forces you to play tactically.

Cons:
Higher velocities (if the gun is already shooting hotter than your liking).
As explained above, these don't like full auto much.
PRICE. GBBRs will always be expensive in all aspects, but that doesn't make paying $30-$40 a mag any less painful.

For me, these are nearly perfect and any minor quibbles are easily ignored in face of all the massive benefits. Buy confidently, but keep in mind that your mileage may vary.

"This is a magazine, so thee isn't a whole lot to say. But I have two of these; One that came with the gun, and one I bought for an extra. (You can't have too many mags) The only problem I have with them is that the mechanism for the bolt catch when the magazine is empty is broken. It was my own fault, as I wasn't as careful as I should have been when taking them apart to clean the dirt I had gotten in them when I dropped them in sand. Thankfully, WE Tech makes a replacement part kit for these and I can fix my magazines with it for 7 bucks. . I keep them cleaned and oiled well. I have had them since Oct. 2016 and I haven't had any issues yet. No leaks or anything. I plan to buy more soon because two isn't enough. I run propane in mine, and I keep them oiled up.

Not many pros or cons, but Overall,

Pros:
Outside is metal, so they can take a beating.
If you happen to break the smaller parts, you can buy a parts kit to fix it.

Cons:
They're $38, so they can get pricy if you want to buy several

As far as my experience goes, these are great mags. Only giving it 4 out of 5 because they're expensive in my opinion, but I guess it could be worse.

Thanks, and have a blessed one!

"Have purchased 2, one a friend and I shared an order, the second, I placed through my account. Ive ordered 2 tan, one black. The most recent tan one I received, I was sent a closed bolt mag, in a box that clearly says open bolt. It chipped my nozzle. I received it on a Friday, immediately sent a RMA request, no response, waited 4 days, called, was told to send pictures, did so, waited 3 days, still no response. When the mags work, they work great. I actually HPA tap mine, so I don't deal with the consistency drop. Love these mags otherwise. would be 4 if they would have not put the wrong mag in the wrong box

"If you live in the southern states where its usually fairly warm year round, get green gas mags. If you live in a cold climate i recommend the co2 mags so you don't have any power loss in cold weather like green gas, otherwise, the first c02 one i ordered worked for a while then became leaky, so i bought another mag and release valve for 9 dollars here on evike.com
