So, I have this really, really nice customer in New York. He placed an order for a fixed M4 Adapter, because he would like to get a better stock. He liked the sound of the VLTOR... but I wanted to know.... What would be a really great stock for him? I don't know much about stocks other than ours, so.... a little help? I want to recommend something to him that he would really enjoy. He's a bigger guy, from what he says, so he'll want something that can extend to be fairly long, and have enough surface area on the butt to resist being swallowed by his "big ol shoulder". Ideas?
