||All I can say is: wow. This is by far the best airsoft gun I have ever owned. I've had this M4 for about 3 months now, and I must say, I am amazed. I recently upgraded the barrel and hop up, which is why I'm writing this review now and not later. The gun is incredibly solid and will last you a long time.
Solid gearbox. The gearbox is a full cylinder, which to me means that this gun is louder than normal.
The entire gun is metal, with the exception of the hand guard, grip, and stock.
G&P's motor makes this gun shoot as fast as a lipo with a 9,6v intellect.
The Gun is wired to the rear with a Deans connector. This is good because you can easily split the gun in 2 without messing with the wiring.
The plastic handguard on mine broke within a week of having it. The only reasons I'm not marking it down to 4 stars is 1. It still works, and 2. It gave me an excuse to by one with rails.
This gun shoots pretty hot out of the box, and I just put a Systema Purple, PCS, and Madbull TBB in mine, which only makes it shoot harder. I'd say im shooting 20 RPS at 435FPS and getting a range of 130 feet.
The threads are 14mm+.
Recommend getting a sight. Iron sights are bad.
Not much else to say. I highly recommend getting this gun over the Matrix pre upgraded one for $10 less. I think that this one will last you a lot longer.
