||I had got one of this mags w/ my SRC gun and this mag works very well. Even though its polymer if you drop it from ANY height on grass ur 100% good, Drop it from 6 feet onto concrete floor ur still good! I'm going to get another 1 to go w/ the 1 i got now. The price is a lil' high but its still a great mag, i recommend this mag to anyone w/ a SRC gun or a gun who has a sensitive mag well.
Pros: 300 rd high cap (normal)
Waffle/Magpul style mag
Cons: Polymer (not really a con to me but maybe to some people)
~ In total i give this Mag a 9/10
