Evike Custom KWA LM4 SRQ Gas Blowback Airsoft Rifle (Color: Black)

"first off its a beautiful gun.i bought the traditional m4/m16 carry handle iron sight just to make it more beautiful. for performance it fed flawlessly, was able to hit within a 12 inch radius from 40ft, and the gas mag can let off all 40 rounds without any significant decrease in fps. has slight wiggle from upper receiver but nothing to be concerned about in my opinion.
