This is a great addition to an ar if you are trying to get the least weight possible - V Seven AR-15 Hyper-Light Magnesium M-Lok Handguard

The fit and finish of this hand guard are excellent. I have had people at the range compliment me on the look of it. It is also so light it almost feels like I don't have a hand guard at all. The install is a little tricky as it involves more timing of the barrel nut than some Hand Guards I've used. However, if you've used the standard style where the gas tubes go in the barrel nut hole then you won't have too much difficulty. The timing is for aligning the screw holes that attach the hand guard to the barrel nut. If the barrel not is not aligned right the Hand Guard top rail will be off. Didn't have any difficulties sliding the Hand Guard over the barrel nut like the instructions warn you about. It was tight but still easy to slide on. I am very satisfied with this part and will consider buying again for my other caliber builds.
