k good!

K, what you have to understand here is this: In the big brand names (E1, JG, CA,G&G,TM,etc), everything works for everything. any M4 mag will work for almost any M4. Same with g36, AK, AUG, Mp5, and every other commonly produced gun. That being said, OF COURSE that mag will work with your gun . As long as it is an M4 mag that didn't come from walmart.

i was just wondering since it didn't show the tops of them

Sorry to throw some water on the fire but......
That is not correct, every manufacture has their own tolerances and construction methods, and tho some types of magazines are compatible with other brands, most are not.
Example,
TM magazines work in a CA M4 just fine, but reverse it and you wont be able to send any BB´s down range, the same goes for Kings Arms, SRC, STAR. It is a shame that most Dealers and Sellers don´t take the time to test and find out what works with what, may have something to do with Copyright Protection, I don´t know.

Your best bet to finding out what works with what, First, hope that somebody here has tried it, Second, if somebody on your Team or A friend has the Magazine, test it yourself, and write your results down for later reference.
