Anything on the market already that would fill the bill?:

Send them the UBR. It’s Ubber Tactical!
Based upon the five specifications listed I would think LMT, Magpul and VLTOR would all be able to comply. While not fortunate enough to have a UBR as of yet, from the reviews of those on this board it appears it would be a great stock for such an application. Of course, all companies listed would be able to provide a quality product. Being biased, I just think Magpul could do it better. Should be an interesting bid/transformation to watch. Makes one wonder why they just haven’t gone all M4 yet though.
