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.

"Fantastic. Tested them to work in: ICS M4, G&G M4, G&P M16, Jing Gong 416, VFC M16, Magpul UAR, SRC M4, Tippmann M4, they feed upwards of 40 BB's a second and are super durable.

Buy five today, you physically cannot regret it.

"I've had these mags for about six months now and honestly I think they are great. When it comes to construction they hold up well just be careful not to be too hard on them while loading as they can split. The material may be on the "cheaper" side but I've thrown them across concrete and they hold up great. One of the main draws to this mag however is the fact that they feed any gun. Countless times I've come across people who's mags are a hard fit for don't feed well and time after time these mags have solved the issue, no matter the BB weight or brand.

Pros: 1- Feeds without fail
2- Great Price
3- Built in hook for ease of use

Cons: 1- Will suffer if the spring is not taken care of every ten or so loads
2- "Cheaper" feel and material then some of the better constructed mags (But
normal care will keep them performing well)

All in all these are amazing mags that I will keep on buying as a great backbone to my arsenal.

"I bought these Mag a While back, and had them for about Half a year, but I think these are the best mags on the market. They feed great look great too and there Built from real Polymer and they can just take a beating. These Mag can fit literary any M4 gun or any gun that can take m4 mags. But over all I prefer these mags over the PTS EPM Mags. There Awesome mags!!!!
