I have a DR200 (post ban K2) that has tuned into a safe queen. I will give some thought to freeing her if you're interested.
She has been converted, 922 compliant with folding stock and 4 rail handguard, an upgrade over the K2. I doubt I have the original thumbhole bastardization stock. I would want to keep the muzzle device since it is a QD for my YHM suppressor. It would have to be replaced with a made in USA to remain 992 compliant.
