This thing was my first mid-level gun. It was also the first one I painted, making it probably my favorite out of the few that I own. It was also my first indication that Jing Gong was starting to step up their game, by packing the M4 in black foam rubber and including GoldenBall .20g bbs. Right out of the box, I was impressed. Although the body minus the RIS is metal, the vast majority of the body is plastic. However, I was shortly reminded that it was a JG when the back sight hook fell out. It's now starting to show signs of wear, but it's still running strong with about 8,000 bbs through it and being used whenever possible for about a year. This is a wonderful mid-level gun and I definitely recommend it.
