Anyone have any experience or recommendations regarding this piece of hardware.  Good or bad?

I knew a guy that bought one about 7 years ago when they were first being sold. After shooting it a few times he refered to it as POS.

It would double, and frequently jam. The guy he sold it to broke the firing pin and it cost $60 to replace.

I have both SAP and SAR. Owned both for 11 years. Have about 4000 rounds through rifle and 6500 through pistol. Both shoot better than 2 MOA. The rifle is mag sensitive, the pistol isn't. No parts breakage to date. The pistol generates alot of interest at the range.(!) Would never sell either. Paid $600.00 for the pistol(new) and $650 (used-98%) for the rifle. Parts are probably unobtainum.
