This thread is a classic case of people throwing shit at something because they are not familiar with it or it isn't their bag. So far, I haven't seen a single answer to the OPs question that wasn't either mud slinging because of personal taste or just outright dogpile trolling.
The specs read like it is a solid stick. The ergonomics are largely driven by the design requirement to allow people to drop in a R700 or similar barreled action and end up with a bull pup bolt action. I have yet to see an answer, other than the perceived LOP argument, that had any merit against this product. And the LOP argument seems moot to the OP, if in fact it is as long as posters are making it out to be (doubtful).
His question was if anyone had any knowledge why this might not be made well enough to perform as advertised. I see no reason that it shouldn't, ergonomics being what they are. It it milled 6160 aluminum, not molded polymers like so many lower end stocks being used by people on this site to good effect. So, a solid and high quality stock material.
As long as the bedding blocks are built correctly, there's no reason that this should be any less accurate or durable than anything else, short of a DT or AICS.
You can continue throwing sticks and stones at it because it is different, because you don't like how it looks, because you dislike bill pups in general or just because it's fun to voice a strident opinion over the Internet about some thing you have no knowledge about. None of these are reasons that should dissuade the OP if he likes it and it fits his need/want.
