It's been a while since I've made a Lego gun replica, and I've wanted to make this one for a while. I'm quite happy with the result. It took me about 12 hours to build, so far longer than any other of my guns have. The Grip was designed by Giovanni Tuzzi. Although I was planning on making many more working features, such as a magazine release, opening ejection port, and a charging handle. But because of the slopes on the top of the gun, the area I wanted to make the working features was reduced to two studs wide. Oh well, I'll just have to make another gun with more working features ;) Any thoughts?
