"Okay, the ICS sportline, nice gun. It comes in a nice box that has a lot of black and red on it. You get the gun, I jamming rod, hi cap magazine, which feeds great (and the wheel is oh so smooth to wind.) You also get a barrel plug, some precision bbs, and with a couple of fuses stapled to the bag, you get some black thing in a plastic bag and I honestly have no idea what it is. It also comes with a manual, which shows the instructions beautifully. Onto the gun, itís pretty much polymer all the way through, except internals and the buffer tube, as well as the outer barrel. The plastic is really nice, better than G&G. It has a boring old fixed triangle sight, and a rear sight/carry handle. The hand guard is plastic, like the body, and it wobbles slightly. If youíre buying this gun, itís purely for performance, because internally, this thing is a beast. The trigger response is amazing, I was using a 9.6 nimh, but Iím sure this thing can handle up to an 11.1 LiPo. To get the battery compartment, you have to unscrew 2 screws at the stock, and pull the back off. I wish ICS wouldíve just had it be so that you can just pull 2 tabs and it would come off. Overall, the performance of this gun is itís main feature, for me at least. The externals are boring, but that doesnít matter because the internals make up for it. I highly recommend this gun to anyone looking to get into airsoft or for someone who needs a backup gun.
