Really like the Hand Guard. Provides a continuous top rail for that Monolithic look at the best price for the 308 setup. Less weight than similar fore-ends. Good gripping surface as well. I'm not a gunsmith but have a basic understanding of AR style builds.
Pros: User decides how much and where rails will go. Keeps weight down while still allowing the need rail space for accessories. Smaller Diameter of Hand Guard is more comfortable than the regular 308 systems.
Cons: Need to use AR-15 Wrench rather than the normal 308 wrench
