I built my first AR about 3 years ago and it's been a great gun. I have recently been wanting to lighten it up a bit since it does seem a bit heavy and anybody that holds it for the first time says just that. Anyway, kind of on a whim, I started looking around and ran across a Diamondhead VRS hand guard. The more I looked at it the more I liked it. So, I found one for a decent price and ordered it, along with a PWS FH/comp and a low  pro gas block. I replaced the Badger Ordnance hand guard, YHM FUFS/gas block combo and a Smith Ent. Vortex FH. Wow! what a difference in weight and feel. I really like the Diamondhead hand guard and I'm sure I will like the PWS comp. I have one on my other AR and really like that one. Anyway, here are the before and after glamor shots.

Good choice on rails, that rail you had before looks really beefy!!!
