    "Awesome mags, never had a leaking problem that was due to poor quality but was my personal fault for improper storage. Great gas efficiency allowed me to get at least 2 full mags ~80 rounds with full velocity out of one fill up and minimal cool down affects. Not as affected by cold weather as most other mags, still got 378 fps with .28 in a 16" DMR kit in high 50 degree weather. Worth the price.

    "These mags are awesome in the G5. They give the super hard kick and high fps you want for outdoor play. I personally run G&P usgi and pmags in my G5 when I play indoor, you just have to remove or disable the valve delay mechanism. You loose about 40 fps, and a significant amount of recoil with the G&P mags

    I know EVIKE advertises these as 40rounders but they definitely are not. They hold 38 and if you over fill these mags, the plastic feed lip will crack and lead to issues. Its only a few bucks for a feed lip, but you have to order them from overseas.

    These mags don't leak at all, so long as you keep them filled a bit. I kept gas in one for two weeks and it hadn't leaked at all, still got 50 shots off it. You should NEVER leave a gas mag empty, the seals will shrink and you'll develop leaks, keep some gas with oil in your mags at all times and you wont have as many issues.

    You might hear people complain about these being difficult to load.. just leave em half full for a few days. that will break them in a little, they definitely get easier over time too. Use the little adapter to fill the mags, DO NOT try and fill them from the top with a speed loader like you can with the G&P mags. It takes me like 4 minutes to load 8 of these if im not distracted.

    Also, you can pretty easily over fill these mags with gas, when you fill these, give em NO MORE THAN 5 seconds of gas. GHK has a video comparing an overfilled mag and one filled right and the difference would surprise you.

    And finally, if you want to run G&P usgi 50 rounders, you'll have to super glue a shim into the cutout where the mag-catch catches the mag, these mags sit a tiny bit too low and aren't very efficient with a gap between the nozzle and gas route. I used barrel shims from a delta ring set, put two layers right on the upper edge, and now I have 50 round mags that kicks alright and shoots reliably at about 300 fps. Oh and in case you're wondering, G&P mags will engage the bolt catch just as well, if not better than these mags.
