Most of the reviews I've read have been positive if the reviewer went in with an open mind and understood the purpose and limitations of the design- which some obviously don't. It's based off of a US Marshal's design and works well within a fairly narrow set of parameters. That said, there are videos of folks hunting with it and there is a SB brace kit for it; it's also a good route to go if you plan to stamp it (SBS). If nothing else, it's worth it for pointing out the ridiculousness of the arbitrary laws making up much of the NFA rules.
One of the old timers on Henry Rifle Forum has 2 or 3 of the Shockwaves and says he loves them (obviously he must with 3). I don’t have much use for a shotgun like that, but apparently there is a market for them.
Just ordered a Stag 10 from FOC this past week, can’t wait!JUST finished an AR 10/STAG 10 in .308 Win ! Now to give it a run!
