"Very good product! Shipping was incredibly fast and the quality is amazing. You also need to buy extra 9.6V batteries and a 9.6V battery charger. Also purchase 6mm .25 g bb’s and extra mags to have a really nice setup! 10/10!

"Bought this gun a few months ago and have played in many skirmish type game, and I am truly in love with this thing. I originally was nervous about buying it because it did not have too many reviews, but now that I have played with it numerous times, I definitely feel it was the right choice. I wouldn't reccommend this for CQB, but I can definitely recommend it for outdoor play. Im not sure if it is just my gun, but the bb's seem to move too fire too powerful for the hopup to work properly with .20s, causing it to curve up a bit no matter what, however, using .25s fixes this.

-Relatively lightweight
-Amazing range and accuracy
-Feels extremely sturdy and balanced when holding it
-Very good trigger response with charged batteries
-Plays as aggressive as it looks
-Easy to take apart and clean

-In CQB it's a little unweildy because of it's size
-Battery connection sometimes catches when trying to shorten the stock
-Had to buy seperate keymod rails for a foregrip and attatchments
