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.

"I purchased two of these, sceptical of the reviews but they work perfectly.

"So I ordered the 4 pack, not a single one fed properly after about 2 hours spent just trying to break them in. Plan on returning them

"This mid-cap mag for P90 eliminates the infamous feeding issue of the hi-cap P90 mags. But the product is not without issue, which can and must be solved for this mag to be really useful.

The issue is that the feeding spring in the mag is too long, creating so much tension that there is no way in the wide world for the mag to accept the 170 rounds that the product name indicates. At least, this is the case with the ones that I have purchased. If you force it, your speedloader will probably break, or bbs shatter, or both.

You basically have to take the mag apart, pull out the spring, cut about 5 inches of it, put the spring back and reassemble the mag. With this work, the tension is such that you can probably load closer to the advertised 170 rounds. There appears to be some variance among these mags with the length of the springs, so you may have to cut more or less depending upon which spring you have encountered.

Once this is done, this mag performs well, virtually never encountering the feeding issue.
