Product Information:
First of all I understand why this magazine isn't in stock anywhere that I can think of. It is a well-rounded magazine that follows KWA's motto "Engineered to Out Perform."

-Unaffected by cold temperatures
-Extremely gas efficient
-For mil-sim players, weight of fully loaded AR-15 magazine
-40 rounds rather than traditional 30
-Feeding lip helps decrease jamming

-For mil-sim players, 40 rounds not realistic 30 round
-Heavier than most mags
-Tend to start leaking a lot

Product Information:
Biggest reason to buy these? There the only magazine compatible for your LM4 other than the PMAG.

The STANAG style mag is the better option of the two for a few reasons...

1) They rarely leak and if they do its a extremely easy fix.
2) They hold 40bbs in comparison to the PMAGs 38
3) They hold more gas than the PMAGs
4) They're lighter than the PMAGs (3 PMAGs weigh the same as 4 STANAGs)

- High gas capacity, you'll get 2.5-3 mags worth of shots.
- Very durable materials
- If you break the feed lips you can easily replace them.
- Holds 40bbs

- They can leak, if they do replace the middle release valve o-ring with a larger one and all your leaks will stop.
- The finish scratches off rather easily, a stronger coating would have raised my rating to 5/5.

I got my lm4 from AirsoftGi about 5 Months ago and all I can say is this gun is solid. The mags are great. Their build like a tank I've had no problems with feeding or gas leaks. the mag hold plenty of gas I get about a mag and a half each time I fill it. A lot of the gas guns I've had it the past I alway had problems with the mags leaking or Jamming and the Cool down effect. But one thing that mite be a con for some is the weight of the mag but its not a con for me. All an all a great Product and I'd recommend it to anyone looking to get a gas gun that will last.

Holds a good number of bbs (40bbs)
Hold a lot of gas
You can buy replacement parts for it
No jams or leaks
Realistic weight

None (Other than weight could be to someone )

This is a great product. I like this one over the Pmag since it is cheaper and it holds 2 more bbs.
DO NOT PUT IN MORE THAN 40 BBs!!! It will jam your LM4! If you fill it up to the top and the bb is on the left it is holding 40 bbs however, if it is on the right, you may have put in a extra bb. I just pop the top one off every time. Better have 1 less bb than a broken LM4.

I use propane in mine it works great. It just that you need to put in the right amount of silicone or your o-rings will get dry causing a leak.

Just get a valve key. Every GBB user should have on in their tool box.

- I love low cap magazines
- Works in the cold. I had this this wet and it froze the water but it still functioned. it is awesome!

- Heavy
- May leak if you do not lube it properly
- Cost? It's a gas-in-mag system it should be.
