"For the price point you really cannot do any better; trust me I’ve tried (been playing airsoft for almost 20 years and have owned over 30 rifles). Bit since the other hundreds of reviews online have told you this is a great gun for the price, here are my thoughts on the features I like/dislike.

Chrono’d at an average of 350 FPS with .25’s after I put about 1000 rounds through it. Currently shooting 24 rps with a 15c 11.1 LiPo. FPS is very consistent shot to shot (less then 5 FPS \-) which is indicative of a nice air seal. Accuracy and range are excellent stock based on my experience (I’ve seen others gripe about the hop up on KWA’s but that was not the case for me). Hitting an Evike popper target at 50 yards with acceptable consistency. Variable FPS is an awesome feature to fine tune performance without having to change springs. I also love the cut off mag feature since I hate dry firing (basically telling the other team I am about to reload so please rush me). Fit and finish is on par with every other high end gun I’ve owned. Eligible for Evike’s bonus program so you can pick up a spare mag or other goodies for free also.

My only gripes are the wiring in the buffer tube is too long and too thick (think desk lamp sized power cord rolled up inside a buffer tube). Not a big deal if you have the tri-cell style lipo’s; also a small 11.1 LiPo will fit vertically in the stock end cap. Other concern is the durability of the cutoff mag. I haven’t attempted to use them in any type of fast pace game where rapid reloading is needed, but I’m concerned the bb follower protruding from the mag will break off if rattling around in my dump pouch or if the mag is tactifliped to the ground during an engagement. Neither of these are even close to deal breakers; more info for you to consider.

All in all it’s a great rifle and you won’t be disappointed

"This gun is amazing.

-Full Metal
-Crazy reinforced THICK gearbox(can handle 500+ fps)
-Very well Shimmed
-VPS is very easy to use
-Motor can pull m125 spring no problem (VPS set to its MAX, 467.41 fps)
-High Speed Gearset
-18.3 rps at 388fps .20s average(VPS tuned all the way down) with 9.6v nimh 1600mah
-Electric cutoff and functioning bolt catch
-Ambidextrous fire controls
-PTS enhanced motor grip never comes loose
-feels like it has a mosfet, it doesnt.
-Cycle time: 36ms with 11.1v 35c 2000mah at 388fps (thats baisically instant btw)
-One Piece rotary hopup
-Contact Protector Means you can use an 11.1 35c 2000mah and have no worries about your trigger contacts

-Hopup bucking is being a bit fidgety, only hoping about 1 in 3 bbs properly (it still hops them, just not as far, might be the bbs, i only had blackops bbs to test with)
-Only one steel tooth on piston with non-ported aluminum piston head(I do not recommend this piston for over a 9.6nimh battery and anything past 420 fps. otherwise it will shred)
-Does not accept GATE TITANS or BTC Spectres
-Orange tip came with glue on it, most KWAs dont
-Mock Bolt doesnt always lock back

Other Thoughts:
I was under the impression this gun had a 2-piece hop up and, like a traditional kwa, swiveled open like a real AR or a GBBR. IT DOESNT. DO NOT TRY TO DO THAT EVEN THE MANUAL HAS IT WRONG. The receiver separates like a normal aeg, but you may have to pull the charging handle back to remove the upper.
