"I have an King Arms M4 CQB and was so disappointed with the 50rds mag that comes with the rifle, I also tried an G&P 50rds mag and had the same issue, the leaking, so after a few researches I decided to buy the G&P 39rds PTS Magpul mag and now I am pretty convinced that this is the top of theine on GBB mags. I just test it today and I was able to shoot 3 full magazines plus a few more shots with just one refill of gas on propane for a total around 120 bb's without refill it again. I do recommend this magazine, also Im planning to buy a few more.

"I wasted a lot of money on poorly manufactured G&P gas blowback garbage this year. The G&P GBBR VPR rifle is garbage and these magazines are garbage. If you want a well-built GBBR, buy a KWA LM4 or even better the PTS model.

Also, let me be clear: these are not Magpul-built magazines. They may look like Magpul, but they are not.

"Amazing at first. I bought four of these mags, and I loved them for about four months. Then three mags started leaking. I bought a ton of o-rings and never got a good seal again. I just tried to caulk them shut. I have no clue if that will do it.

"These are the only magazines I use, mostly because other ones are out of stock, but these ones are also probably easier to maintain as well.
Let's start from the top to bottom for pros:
-feed lips are metal, no wear with the original G&P bolt.
-fit great in hand and just feel natural reloading
-have base plates on the bottom to protect the fill valve or for mag pulls.
-retain gas EXTREMELY well, if you take care of them!
-o-rings eventually popped out, have to buy the moondog ones to replace them.
-mine have a hairline crack on it, though it doesn't leak it worries me
-paint on the back has worn down completely, just file down the back of your magwell to help stop it.
-you have to tighten these A LOT after you put them back together, unless if you have a bit of man-power, use a drill and slowly turn it with a wide enough bit to tighten it. Mine used to leak, but after using some man-power, they're tight enough that they do not leak.
overall: would recommend these for your GBB, good price compared to having to buy ones from over seas or waiting for G&P WA mags to come back in stock, they also have a nice look, since they're made by Magpul of course. Reason for 4/5 is because of earlier lack of man-power.

"These magazines are the absolute bomb! They operate perfectly, no leaks and very economical on gas. But don't drop them however, I dropped one by accident and now it leaks.. Anyway, I would recommend these over any of the others sure they may be a bit pricey, but its worth every cent. They just need slight sanding on the sides to fit into the magazine well properly and they are good to go.

"I suppose I could start by saying that these mags feel great, they have the weight and heft of a fully loaded RS 552 mag, however, I am disappointed because I bought two of these mags, one leaked after only three uses, and the other leaked right out of the box, they both leaked from the top seal (O-ring) and the last one I got actually leaked from the output valve, I'm hopping that 'soaking' it in silicone oil will fix that.

Would I recommend it?
Yeah, sure. If you don't mind repairing/changing the original O-rings.

"These are great magazines, and are much less expensive than Pro-Wins. I have had no trouble whatsoever using these in my G&P WOC build. They have a fair amount of heft to them and weigh a little more than a fully loaded real-steel magazine- I'd say between 50-75 grams more.

I prefer these to the standard STANAG style G&P magazines because their design allows you to quickly address any internal leaks by tightening the screw that holds the three sections of the magazine together (located under the spring-latch that holds the Magpul baseplate on).

Make sure to keep the internal and inlet/outlet o-rings lubed and this magazine is sure to perform well. On a good day I can easily let off 4-5 loaded magazines (30 rounds ea.) on Semi with one fill of propane.

"This is the best magazine for king arms, wa or anything that these will fit. They feed flawlessly, less prone to leaking(compared to other mags). Also they're cheaper than other mags out there. Not to mention they look great!

"I currently have two of these mags for my g&p WOC challenge kit m4 and they work amazingly! They feed very well and they are super durable( they are metal) . I've only had one problem with them. Since the mags are built in 3 separate chunks with big o- rings between, there is a big screw that hold it all together. My mags leaked a tiny tiny bit out one of the cracks and to fix u just have to fake the bottom plate off, pop the pin out that holds the grey lever on, then the screw is revealed. Tighten a lot to hold the mag together tighter. I did that and no more leak. The fill valves are very nice and have o rings so they don't blow gas everywhere. All in all these mags are very nice and work great. Best mags I've used and need to get more.
