MAG Why Mid-Cap Magazines?
Mid-Capacity magazines offer stealth operation by eliminating BB rattle often experienced with Hi-Caps. They feed smoother than Hi-Caps due to their high tension internal spring, similar to a real steel magazine. Since 470 round Hi-Capacity magazines don't exist in real life, a good amount of Mil-Sim players prefer Mid-Cap magazines for an even more realistic type of gaming experience.
Due to the design of all Mid-Cap magazines, they actually function better once you break them in. To do so spray some light silicone oil into the magazine, load and unload it a few times until BB's feed smoothly. This process breaks in the internal spring allowing it to function without problems each and every time.
"So maybe I was given lemons, because my experiences were nothing like the ones in the reviews below me. I have tested these mags on 3 different guns and every time the results disappoint me. Allow me to explain:
I purchased 2 of these magazines about 3 years ago, and used them in my JG P90. After breaking them in, they worked pretty well... for a little while. After a few weeks they started to jam and misfeed 1 bb every couple of shots. Eventually it got to the point where it wouldn't fire up to 5 bbs at every few shots. It was getting pretty ridiculous so I simply just stopped using them and let my friend use them for his P90.
This is where things get even more outrageous. My friend who also own a JG P90 used these mags and for some reason 1 of them fed almost perfectly, and the other hardly fed rounds at all (at best it fed like 1 every 2 or 3 shots).
I decided to disassemble these magazines, which is actually quite easy, and clean them out entirely. I washed everything from the casing to the spring, to make sure their wasn't any dirt or unnecessary oil inside. After spending an hour doing so, I reassembled the magazines and kept them in storage for about 6 months (I didn't have a P90 at the time to test them).
Now today I was finally able to use them in my brand new Echo 1 AR-57. The gun itself is absolutely amazing and I have no problems with the included 68 round magazines. However once again I experienced difficulties with the MAG midcaps. Luckily, one of them (the good one) doesn't misfeed frequently. Every 5 shots it misfeeds 2, then works for another 5 and misfeeds another 2. It's basically a 5:2 cycle until the magazine is empty. On the other hand, the other magazine is like the complete opposite... it's more like a 2:5 cycle where it fires a couple rounds then misfeeds a bunch.
My assumption is that the springs are weak in these magazines, because I am positive that it isn't the guns' fault. I'm not sure if they are worth replacing, but that it my best guess as to why these problems are happening.
So there ya have it... these didn't work very well for me :(
However, because these magazines are rock solid and hold an enormous capacity for a midcap, I have given it 3/5 stars. I think that the design is good but the spring they used could have been a lot stronger. I will update this review if I end up finding a solution to this problem. For now I suggest getting the 68rd low-caps. They might feel cheap, but they are the only magazine to function flawlessly in all 3 of the guns mentioned above. The King Arms midcaps also look promising, so those might be worth a shot. As for these and the hicaps, they aren't worth your time.
"These are the most reliable and fastest feeding magazines I own. Aside from the break-in period, where all four jammed at once, they have been a P90 dream. Its strong spring makes this magazine a must have for high speed builds.
"Excellent P90 magazine. Built extremely well, the plastic is solid and has absolutely no flex in it at all, unlike some other P90 mags. Considering the price, these are well worth the money.
