"I figured its about time i give some reviews to good and bad products. So. buy this gun. Just do it. If you are a new player and want a great gun off the bat, this thing is perfect. Experienced player looking for a good reliable gun? Buy it. It has awesome accuracy right out of the box, a better than average barrel that adds to that, a sweet rof for a base gun( get a 9.6 starter or a lipo, not an 8.4), and a more than decent velocity, right around 370-400 with .20. The gun is heavy, solid and just looks bada** ( i have mine upgrade to be a dmr with an m130 spring, g&p bucking and an aluminum anodized piston)
PROS: Solid for days.
Sweet accuracy
Built incredibly well
Good stock rof
Good stock fps
Good stock range
Full metal construction
Picattiny rail system is awesome for adding stuff
Lipo ready

Cons: Your friends will hate you if you upgrade like i have.
You need a battery.
Heavy (con for some)

all in all, this gun is excellent in quality and performance and is even better when upgrade
i personally suggest an 11.1 lipo or a 9.6 with it , extra mid caps( dboys high caps work well with it too), a fore grip and sling
and maybe a red dot or optic if you like that. BUY IT,

"First off, I just want to clear up something I had trouble finding out; you can in fact put a Madbull Mk18 rail system on this rifle. Second off this rifle is great for Milsim, if you are typically sprinting up and down your indoor arena every other Saturday, I don't recommend you buy this gun. However, if you would like a nice rifle that will hold up for a long time and serve you very well, buy this rifle. The only internal upgrade I have in mine is a G&G green hop up bucking, and it fires great. I use this rifle for my assaulter kit, but due to the customizable nature of the M4 platform, this could be turned into a DMR, CQBR, or even a Sniper rifle if you really wanted. 10/10 would buy again.
