"I was a bit skeptical about getting this because people said things about stock wobble and R.I.S wobble and the abs plastic receiver. So I overlooked that and got it anyways and to this day no regrets. I've had it for a day now and I love it! So so accurate best gun under 200

Rail covers, foregrip,battery
Loud-I like loud airsoft guns
Looks great
Upper/lower reciever is super high quality to worry about it

Slight slight wobble of crane stock
R.I.S. moves back a centimeter when you pull back(can hardly even notice it) really don't worry about those two

"Very Nice Looking! But When's i got it I loaded the mag up and did the rotation and Then out it in my AEG it didn't shoot at all so I took the mag out and re rotated it and it shot 3 NBA then wouldn't shoot again....... It doesn't shoot right:(

"I got this as my starter gun, and I'm very happy with it with one gripe: the weight.

Excellent Hop-Up
Great Range
Good Accuracy
Comfortable Stock
Lots of Battery Space
Good Stock Battery
Long Battery Wire (so you can change battery w/out collapsing the stock)
Included Hi-Cap Mag, Foregrip and Rail Covers (all good quality)
Sling Mount Points
Working Charging Handle (F-ing COOL!)

Laser Engravings (some are cool, some just look like an edgy 12-year-old put them there)
Charging handle doesn't lock back so it's kind of hard to adjust hop-up (but my hop up was great out of the box os idk)

Front RIS is slightly wobbly rotation wise (especially apparent when using foregrip)
Safety selector (my field is semi-auto only, and I find I frequently bump the selector out of position)
HEAVY (this is my major gripe. It feels beefy, sure, but it'll soon tire your arms out)
