I'm liking the versatility of the Magpul PRS but the damned pricetag is holding me back from nabbing a couple of these for a pair of rifles that I'm building with my Dad. Shopping around online, I found Luth-AR's MBA stocks. They appear to be just a little more versatile than the PRS by allowing multiple positions of where both the LOP adjuster and upper comb can be mounted on the stock, as well as a bit further adjustment on the LOP. Anyone have any hands-on experience with the MBA stocks? The price is almost half of the Magpul, so that in itself has enticed me to want it...plus the added adjustability is really driving me towards them too. I'm sure I haven't shopped all my options out, but these 2 options are pretty close to what I'm after -- planning to mount it on a fixed rifle buffer tube assembly. Any other adjustable makes out there that I'm not aware of that would suit my wants/needs/wallet??
