Which Battery?

Hey guys, I haven't been on for like 5 months but w/e... I finally i think I have chosen a gun to buy: Combat Machine M16 (http://www.airsoftpost.com/product_info.php?products_id=30418). Now I know it doesn't come with a battery, and that is what I need. Which one to get?

Thanks

Haha silly Evike, that's an M4A1 not a M16. Good thing i looked at your link or else i would of said a 9.6 large type battery. I'd highly recommend getting this battery, http://www.airsoftpost.com/product_info.php?cPath=31_169&products_id=24484. I use it my KWA M4A1 and works great and fits perfectly inside the hand grips. Plus it's 2000mah so more a little more power and it'll last longer playing.

haha i thought that was an m4.... well thanks. that is really expensive though

It's not too much more, and the little extra cost is well worth it in my opinion.

alright ill probably go with that then. thanks a bunch. would you say going with this gun and buying this battery would be a better idea than going w/ and echo 1 g36c and staying with the battery it comes with?

My brother has that M4 and two buddies of mine have the E1 G36C. Personally i like the feel and build quality of the M4 over the E1's and the ROF is a little better as well (if that matters to you) by using a 9.6 battery over the 8.4 the G36 comes with. The E1's though have more power out of the box though, my bro hates using his in the woods since it only shoots around 315fps and can't punch through brush very well.

ok thanks for the information

Oh and are you absolutely positive that that battery you suggested wont overpower that gun?
