JG G36k, JG M4 Carbine or JG M4 S-System

I like both of these guns a lot but i don't know which to get.
Here are the links...

Thanks in advance

depends on what you want, if you want better ROF get the G36 but if you want power with a slower but decent ROF than the G36 get the M4... i personally like power, so if i had to choose between the two models i would get..... http://www.airsoftpost.com/matrix-eagle-custom-lipoly-ready-m4a1-piece-barrel-full-tune-380450-p-29002.html it is a pre-ungraded JG m4 A1, the pre upgraded parts are a high torq motor and gearbox and other little details. it is a little bit more money but it is totally worth it in the long run.

I've heard SUCH great things about the JG36, I would have to suggest that either way.

Get the g36. I just got a g36c and power is no concern it chrono's at 380. It is a beast, so GET IT NOW!!!!!! Plus it has great rof on the stock battery.

I would go with the m4 kkoerber sent a link to... i have it and its amazing

if you want an s-system i would get an jg pr upgrated 2008 version. here is a link. http://www.airsoftpost.com/ssystem-enhanced-upgraded-version-airsoft-rifle-black-p-27777.html you can also get it in tan...
