"Great gun, used it for the first time recently and it worked great and it was very accurate. Now I'm pretty new to airsoft so there's problem something wrong on my end but the gun was only chronoing at about 262 fps with .20 bbs but again I probably did something wrong but idk overall amazing gun.

- Well made.
-fit all my m4 mags well, full metal high cap mags and the cheap plastic ones.
-low fps (which again is probably something on my end)

"Had it for about three months now and besides cracking in the middle of the reciever because I ran almost straight into a tree, it is a great gun. Got the matrix battery and it works fine with it nice and light. Hop up style is a little simple but effective. Great internals haven't had a jam even after repeated operator slides. Solid 8 out 10 for a beginning gun! Already looking for upgrade though.

"This gun is AMAZING. Even when put at about 80ft from A target i was able to accurately land shots on target all though they were behind thick shrubbery
