"The G&G Challenge Kit is an excellent base to start building your ultimate airsoft weapon. I purchased this Kit about a month ago and, after installing all the appropriate upgrades, have found it to be a formidable weapon on the airsoft field. I currently have a 509mm inner barrel, 9.6 volt battery, and an upgraded hop-up system in mine. Shooting .28s I consistently fire at 310 fps and have outstanding range and accuracy. The rate of fine could be a little higher, but since I mainly play using mid-caps and on semi-auto this is not a big deal for me. The high-cap magazine that comes with the gun is great quality if you plan to use it. This gun is easily matching/outperforming my other ICS AEG’s with similar upgrades and it is already my favorite gun in my arsenal.

The only thing I was unhappy with in this gun is the large, ugly evike logo on the right side of the lower receiver. The logo was annoying to remove but a small price to pay for an excellent gun.

I highly recommend this gun for intermediate to advanced airsoft players. With endless upgrade options this gun is only limited by the builder’s imagination. It is the perfect gun for players on a budget.
