So I've been doing some more number crunching over the last couple of days, a little price comparing at such, i might get a Knoxx NRS from TSE (probably just send the money to my sister in Calgary and have her pick it up to save on shipping) but the same problems keep coming back. It all has to do with grip geometry. in order to get the stock as straight as possible, the grip will invariably be at a wonky angle. I'm trying to keep the grip angle as close to what an AR15 would be.
So I got to thinking (again) that I could make up a plate that I could bolt either the adapter from Vz58.net or a modified Rauch Tactical adapter (I'd have to grind the bevel out) and then weld a mounting point for a pistol grip. I've got some 1" wide flat stock kicking around my storage room that I could heat and bend into shape, and then grind the contours as needed, and then anchor that to the stock with some bolts and epoxy (a setup like this I wouldn't be too hurt about trashing and redoing since I have two three foot sections of flat stock.)
I don't have a CAD program available to me, so my designs would be of the pencil, paper and ruler variety, unless I can do it in MS paint, so I'll post it up once I get some time to draw it up.
Now, before I get too carried away... does anyone see any major flaws in my plan?
