Looks really nice; I want one. I have a question: what is the purpose of the pistol grip on the forend? I can see how it could be useful on full auto, but to me it looks like it mostly just makes the rifle that much more end heavy. I've never used one though, and a lot of ARs have them, so there must be some good reason for it besides looking cool. So what is the reason? Maybe I'll want one.
