I had to make a hard choice, deciding between the rifle pictured above and a regular M4. After a LONG though process I went with the regular M4 (the one with the 14.7" barrel so you can have an A2 flash supressor). I like the concept of midlenghts, like their function and their looks. It's just that I wanted something that looked very different from my 20" A2. But damn, that midlenght is beautiful!
