"So I've had this gun for a year now and it still works perfectly its pretty light and nice to and I'm really short I only gave this gun 4 stars because of the poor battery compartment ya you can fit an 8.4 perfectly but no one wats to do that. I bought a battery bag and custom wired it to the out side it worked perfect around 20 reps with a 9.6 I have an 11.1 lipo now and its like 25 rpshighly recommended.

"after buying this gun i was very disapointed to find that the battery compartment was the worst battery compartment that i have ever seen, i couldnt even fit an 8.4 1100 ni-mh into it. after switching out the hand guard for a more classic versoin of the m4 hand guard, the gun worked great, at 420 fps and a 25 bb's per second rate of fire, this gun dominates at any airsoft field. i give this gun 4 stars becuase of the terrible battery compartment and becuase after buying all the replacement parts the gun came to a huge 500$ price.

"So I picked this M4 up because of the great things I've Heard about KWA airsoft guns... I get the package in with all the bells and whistles I ordered with it, and low and behold I'm one of the few that have the semi-auto fires auto problem. I contact Evike and they tell me to take the gun in and they'll give it a look. Turns out it was a easy fix, which is on the KWA web site. When the battery runs low it somehow causes a timing problem. The fix is to charge the battery (of course), and burn off like 50 rounds in auto. case closed. Evike handled everything with a smile and even took back a item I bought that I didn't need (to my surprise because they have a all sales are final rule. That rule being mostly for people that just buy stuff on a whim and return it later)

Great gun and great store!!!!! They'll Have my business from now on
