"Overall this gun performs absolutely amazing. I installed a TBB barrel, a raptor's full metal teeth piston and currently a matrix irregular pitch M120 spring. With an 11.1 lipo my ROF is 22-24 bps even with the stronger spring. I am easily engaging people at 75-80 yards, way outside of their range.

FPS (even before upgrades)
Full metal
Top notch internals

Heavy after awhile

Thats the only con about this gun, it shoots 400 fps for me now and i've had this for about 4 months now and i can hit people at events from over 150+ feet with this which is really far. Get this gun it is worth every penny and you won't regret getting it. Search supahcrewairsoft for airsoft event videos on youtube.

"I bought this gun about a week ago. It has maintained performance, but as I assume the fps will drop after about a couple thousand shots from breaking the gun in. It's a little pricey but worth it if you plan on fully upgrading it. For it being Full Metal it is a heavy gun and very realistic. Only two things I noticed on the gun that were not metal was the polymer stock, pistol grip, and the internal hop-up. I recomend taking the route of G&G. I have talked with several people who have bought products from KWA and although its a fancy shmancy gun it isnt worth spending all the money for it.

-Full Metal
-High performance bucking
-2Gx internal
-Full Metal
-Full Metal
-Full Metal...
-Lipo ready
-Cranstock battery compartment

-stock is a littler wobly; maybe from packaging and handling or the heavy battery that I have in it.
-Front rails get wobly
-A little loud, im not saying loud is a bad thing but the motor could be better. It just doesnt sound like its feeding right.

Other notes.
-It would be cool if they would include an extra black flash hider to replace the orange one.
-KWA manufactures take forever on giving out pre-orders. Do not pre-order a gun if you are an impatient person.
