I've decided to set my MP sport up for a 2 point sling. I am also considering buying a second non scoped upper for closer target shooting. I use my gun for 200 yard coyote hunting and since it would be my hunting upper part of me thinks I should put a free float rail on it. But I'm poor and I have no use for a rail except as a sling mount. Should I just go with a magpul Moe hand guard?
