Missing hardware, no instructions - FAB Defense Ergonomic Folding Pistol Grip for M16/M4/AR15

The grip is cool, but is missing the hardware. No instructions, but if you can install a standard pistol grip on an AR then you can do it on this one too, but first you have to get a Cap Screw-type AR pistol grip screw. Luckily I had a few in my AR spare parts bin. Now mine wouldn't fit on my particular weapon because I had a QD buffer tube end plate with the "ears" on both sides to clip on the single point slings, or the HK-type sling swivels. The "Beavertail" that extends just wouldn't let me seat the grip all the way down. No worries, as soon I will be changing everything out on the rear end anyway, as I will be adding a QD stock removal plate/assy. (one of those Stern Defense "rapid attach" buttstock adapters.) This weapon is an SBR that I Form-1'd a few years back and decided to put on the Pantheon Arms Promethius QD barrel adapter and installed that tonight with my 10.5" barrel w/A-2 FSB that was originally on it when it was still a pistol before the Tax Stamp got approved. Anyway, this is going to be a lightweight, simple, "K.I.S.S." - type of gun, The Eotech and heavy RRA A-2 fixed BUIS mount that was on it previously came off, and on goes a light, cheap Magpul MBUIS rear sight (for now). When the folding pistol grip finally gets installed (later) this will be a small, light, and handy SBR that I can also quickly attach a can on as well thanks to my YHM Phantom QD flash suppressor. And can be broken down into 3 small parts and put into something very small and be put back together and into action in less than 30 seconds.
