I had a H-1 (no NOD's) on my 14.5", but I moved it my 11.5 & replaced it with a Mk 6 TMR-D. Add a Surefire light and the rifle [upper] is definitely NOT
a lightweight, but with this setup it can do anything from CQB (ok, indoor range) shooting to 400m+ and is really a jack of all trades setup, IMO.
Here are some rifle pics since I've never actually posted this setup. The rail section near the muzzle is a temporary addition to mount abipod when I zeroed the scope. I haven't bothered to remove it yet.
