This is a great airsoft rifle! Its very comfortable and easy too hold. The rifle itself is amazing stock without any internal upgrades. It has a steady fps of 390 on mine. However i have 3 springs and each one varies its fps. It is very easy to switch the springs also. The gun has excellent blowback, that is a plus on it. With the 11.1 battery i was using Turnigy NanoTech 2000mah 3s i got a rate of fire of 16.4. The magazine has a nice cut off feature however you're definitely going to want more mags i prefer mid caps in this rifle. High caps are nice and all but for me mid caps feel and seem the best for it. The rifle is functional with majority of STANAG m4 magazines. Flash mags, Winding wheel mags, mid caps, low caps, you name it. Does not have functional bolt catch on anything other than the RM4 Magazines. The threading for the barrel is 14 CCW.
Weight (For me this is a nice pro, for others its a con)
Has a cut off feature for the RM4 specific magazines
I personally like how its wired to the front
Quick Spring Change
Very nice range stock
The the grip does heat up quiet fast if continuously
11.1 Lipo pretty much required if you want it too last the entire day.
Hop Up on mine shoots either too the left or the right but still has the ability to hit the target nonetheless
