"This gun is by far the best M4 AEG for the price. For $160 you get the gun, which is full metal besides the stock and grip, you get a few Bb's, a cleaning rod, a detachable carry handle, 2 rail covers, and some wrenches. Customizing this gun is easy because there is an insane amount of rail space, and with a bit of work you can remove the front sight for all access to rails. Internally, the battery that it comes with works fine, the gearbox could probably handle an NIMH or maybe even LIPO if you're edgy. The gun does shoot what it claims, I shot 10 shots into a chrono and they all clocked from 435-450 FPS, so it is a very high powered gun. The RPS isn't too shabby, I'd say it's about 9-11 RPS, but that is with a stock battery. By saving money from the VERY LOW costing price, you could easily upgrade that RPS so this gun is unstoppable. The accuracy is very good, and the hop up works fantastic. I shot a lamp post about 100 meters away and the post is about 6 inches across, but in full - auto I missed about 20 shots in 300. Everything the description is true and sometimes is an understatement of this gun. If you're looking to be a badass at the field for a low cost, THIS is what you want. I've spent about $250 in total, an angled grip and a 3-9x30 scope. This gun looks GREAT as a DMR, and works great as well. 5 stars"
