I'll save you from the rabbit hole that I fell into trying to unravel the same question that you're asking. Mark Bansner sold lightweight stocks and rifles at some point under the High Tech Specialties banner. At some point he partnered with Legendary and he did work under that label and they produced his stocks. When they parted ways, it looked like they ended up with his molds and his stock production. He is now getting his own stock production operation up and running though I haven't heard of anyone with one of his stocks yet. You can still get stocks from LAW, but I'd make sure you do your due diligence. There's a ton of stuff out there.
This pretty much sums up what I've been able to discern. The "Bansner" stock is highly reviewed everywhere I read about it but you're right, there are a lot of mixed reviews on LAW out there as well. Seems odd the stock has the popularity it has given those reviews but maybe people are referring to the pre-LAW stocks. And then again, from what I've seen, those mixed reviews don't seem to be directed at the stocks themselves.
