This gun is one of the very best guns i've had. I've owned very nice tompsons, $250 ak's, and a few gas blowback guns, but this gun outperforms them all. It comes strait out of the box with no upgrades in with a 400fps with .20's and 350-360fps with .25's. This gun is all metal exept for the peice on the crane stock you squeeze to shorten it with. I reccomend .25g bbs as it makes the accuracy insane once you adjust the hop-up. The orange tip does kind of ruin the realistic quality of the gun but just cover it with electrical tape. The internals are great, i use a 9.6v 3600mAh Nimh battery.
For those who don't know much about good batteries heres a helpful guide:
Firstly, the voltage DOES NOT increase the fps, it increases the fire rate (rof). The mAh is how long the battery lasts (not how long it lasts as in when you have to throw it away, but until you have to charge it again.)
Secondly and most importantly, the difference and the benifits and doubts or Nimh and lipo batterys. Nimh is an acid based battery. It can also be found in AA batterys you buy at walmart. DO NOT charge these batterys without them being completely dead as it will wear out the bettery much, much faster. With the 3600mAh you will not need to worry about charging much at all anyways. Now, Lithium (lipo's) batterys is a metal based battery. With these batterys you can charge it whenever you want without worrying about wearing the battery down, and it by far surpasses the Nimh battery in how much you can use it until you have to throw it away. If you want to use lipo batterys with this gun PLEASE listen to this. when you are using an 11.1v only hold the trigger down on full auto for at most 3sec as if you do any longer it will KILL your motor and wear your gears down very very fast.
Now that you know a little more about batteries, back to the gun. It is a very nicely constructed, very realitic gun mad of practically all metal. Most m4 mags fit this gun, but keep in mind SOME do not.
all metal (except peice on stock that you squeeze to shorten to stock.)
Very good with most batteries but if yours does not fit tape to outside of stock.
worth every penny
GET THIS GUN IF UR LOOKING FOR A GOOD M4!!!!!!
