Thats my whole thing, while Zenith does have a better finish than POF, its nowhere near the leaps and bounds people make it out on the internet. I guess what I am trying to say is if you can get a POF today its better than holding out wishing for a Zenith that may not materialize.
Or just do the logical thing and buy one of each! (including an HK)
That doesn't look like a B&T adapter on the stock.
The folding stock is B&T and the adaptor is made by Manticore Arms for the SB tactical brace. My Zentih came with the SB tactical brace when I purchased it. As soon as my eForm 1 got approved, I replace the folding brace to a B&T folding stock from HKParts.net.
