Ok … just surfacing to report progress. I have none to report. I’ve altered my target 'cause I decided I couldn’t live with the wonky layout generated by the scope rings.
But, Sunday, some guy posting as casper3oaks over at the KTOG posted this:

And I’m in. IMO the solution is elegant enough to copy. My test tube is currently honed out for an interference slip over and shortened. This morning I marked the tube where the front sight will stow. Once the access/stowage is cut, I will begin drilling the tube for the bolt retainer pin. The buffer tube will actually be fixed in place on the Sub 2k bolt tube with this pin ala factory buttstock, so … once the tube is drilled, the next step will be grinding the pin down near flush with the AR buffer tube.
Casper3oaks rounded the little tube side latch point and glued it to the AR buttstock to hold it in the folded position. I’m not sure I will follow the plan that far. I’m thinking that the ability to tuck the front sight for a nearly complete fold may serve my needs. If not, fixing the latch to the AR Minimalist stock will allow me to lock the stock using the 6 position adjustment.
Here is my dilemma. I anticipate ditching my irons when I install my M*Carbo Flip to Side Optic Mount. If I ditch the front site, I won’t need to stow it and I’ll be wanting a cutout free cheek weld platform. My plan is get the buffer tube cut and prepped but try to hold out finishing the cuts and glue on the Minimalist until my final sighting solution is settled.
I will cut the front off of the Minimalist stock to prevent interference with the charging handle. Hopefully I can retain the QD Sling Mount socket.
And Edit to Add: I’m working with a Mil-spec tube and stock. But, hindsight leads me to confirm that the honing process would have gone much faster had I chosen a Commercial spec tube and stock. The larger bore dimension on the Commercial would simply require less material removal.
