"I just bought this gun last week and it is only my second air soft rifle ever. I am absolutely thrilled with it in all ways; FPS, sturdy weight, ROF and overall quality. I paired it with LIPoLY and smart charger. Worked great after a quick charge. Needed a slight aim adjustment as it shot high out of the box but easily adjusted. The gun has a great feel to it and truly looks as if most anything on it could be reppaired or replaced if ever needed. Mag fit and function was perfect. Came with a tested tag signed by Evikes verifying function and FPS test, which I appreciated. Can't say enough about realistic looks, feel and fit.
So far it has been awesome. Hope to put 1,000 through it this weekend.
Buy the small batt plug to large unit plug adapter if you get the LIPoLY battery set up.
Super fast shipping. Ordered late Monday , delivered by Friday.

"shoots very consitent out shoots my other age's never had problems with the mag feed every bb and stopped on the last shot. i would say to use elite force bbs because the mags are very strange. the a&k mags fit seamlessly. only complaint is the mag release needs to be worked in and no sling points
i give it a 10/10

"Great gun that is 100% compatible with my Systema PTW. The rate of fire is a bit slower than the PTW, motor not as good, but then again, it is not $1200 like the Systema.

Not $1200
