Realistic Knex M 16

So I was looking at the M 16 in this site and didn't quite like any of them. I had tried making one before [my profile pic] but it didn't quite meet my standards. So I looked at TheDunkis ak as a reference and got to work. I wanted to make a gun that fired well, was the right size, had a mag, looked realistic, and could be taken apart like the real thing. With this in mind, here's what I came up with. Hope you like it, leave me comments with questions, comments, or concerns and I'll try to answer as soon as I can.
