Well, here is FlipinCanadian's first crack at the "snap on" Cheek-Riser for the standard B&T Folding Skeleton Buttstock. As you can see from the photos, what he did was form the kydex around the dense foam riser that I had, producing a rounded cross-section (see pics 3 & 4). That was the first thing that I noticed will require some finessing, because the rounded portion on the Right side of the stock interferes with the ability to lock the stock to the Receiver Stud when it is folded. This was not an oversight on Flipin's part, it only happened because he did not have access to the stock mounted on a rifle (mine is restricted) to test in all positions. All he had to go on was my Buttstock itself. The next prototype Riser will have a flattened right-side when you look at the cross-section, which will allow the Stock to latch to the Receiver when folded. Aside from that one obvious glitch, I think that the first prototype turned out very well. We intentionally made it 1" high, which is taller than the foam and approximately even with the highest portion of the Buttstock itself near the hinge. This gives me a very comfortable cheek-weld with the various optics that I have tried (T-1 with FTS magnifier, Burris MTAC in ADM Recon mount, etc). Flippin thinks he may make the next prototype a bit taller still, so we shall see whether or not that fits more facial types.
The Good News: Flipin's idea to use the integral loops of the Buttstock to secure the Riser with Bolts was pure genius. It makes what could have been a wobbly rig totally rigid and secure. There is ZERO play in this riser, which is ideal. The height is perfect for me, but YMMV and we will have to see see if making the riser taller works for a wider user audience.
The Bad News: The use of Bolts to secure the Riser means that it is removable, just not instantly "Snap-on, Snap-off". A small price to pay for the rigidity that is achieved. No, the really bad news is that FlippinCanadian just deployed to Ft McMurray for contract work which may run several months. Arghhh!! Just when we get the ball rolling, this project may have to wait on the sidelines for a bit. Still, from what I can tell you of the prototype, it is definitely worth a wait. The Riser is a game-changer for the B&T rifles when it comes to the use of magnified optics, especially in the absence of any factory solution from B&T.
Here are some pics. By all means, provide any constructive criticisms below for the designer's consideration. As before, I will leave it to FlipinCanadian to determine the production timeline and cost based on his own available time and resources. I'm just the very happy "beta-tester"!

I think that riser has great potential, looks good. I have spoken extensively with B&T about the cheek weld problem, it is simply not cost effective for them to make a mould costing thousands of dollars for the small quantity of snap on risers that would be sold. B&T are looking at fitting the MagPul PRS stock to the APC, right now I am waiting for the price change this would have on the rile.
Sounds like around + $400
If they could make an AR buffer tube adapter then guys could source their own stock and the adapter shouldn't be overly expensive.
I believe that adapter already exists, and is currently available from Wolverine for ~ $240. The only down-side to installing that with a CTR and Magpul Risers is that the stock will no longer fold. So if you don't mind a fixed buttstock, Wolverine can sort you out with an adapter....

Lol! Shoulda sent me a pm I would have bought it back from you. Damn I shouldn't have sold that gun. If the guy you sold it to wants to sell it I'll buy it.
I only fold my rifles so I can put them in a smaller case, other than that I couldn't care less if a rifle has a folding stock.
The most significant benefit of the AR Tube Adapter over the existing stock with a custom Riser will be the adjustable Length of Pull. For taller folk such as Mikethebike, this consideration may trump all others in favour of the adapter. Each to their own. I am very happy with the comfortable fit and minimal cost of the prototyped riser that FlipinCanadian whipped up, but that's just me. Your milage may obviously vary due to body size and/or other factors. I prefer to keep my firearms in factory configuration (less sights and lights) unless there is a compelling reason to second guess the designers and swap out major components. That said, proper "fit" of the firearm to the firer is certainly a valid reason to make or suggest changes...

Hey great job. Question, is the circular profile for ease of forming? Is it possible to have it narrower and hugs the top horizontal part of the stock tightly?
I have a similar aftermarket arrangement for carry handled AR-15's offered back in the 90's. It consisted of a rectangular cheek piece secured with velco tape on the stock--which interfaced with velcro on the cheek riser.
Just a thought as it would be easier than bolting/unbolting something

FlipinCansdian may chime in here if he has the time, since he is the experienced kybdex fabricator. I was just an interested observer, but can tell you that the circular profile was simply the easiest to form around the piece of foam that I had. It also happens to be the most comfortable design in terms of maximum contact area for cheek-weld on the upper half. Version 2.0 will see a flattening of the sides much like you envision in order to reduce the profile. This is particularly important on the Right side, so that the stock will latch when folded. I envision more of an irregular oval shape, with the Right side flattened enough for the stock to latch and the Left side a bit more rounded for max cheek-weld. Unless someone else with Kydex skills jumps in, we wiĺl simply have to wait and see what FlipinCanadian can come up with when he has the time.
Easier yes, but equally sturdy? With the bolts, I can tell you that there is zero slop/play in the riser interface. It might as well be a permanent part of the buttstock. My experience with velcro suggests that there is always an element of "give" or flex to any attachment of parts. Perhaps not so conducive to a repeatable cheek-weld....
Do you mean so it is a similar profile the the stock? It is shaped that way because of the shape of the riser Bartok5 had. If we can find something close to the right height with a better profile it would be possible to make it thinner. The trick will be finding a riser that is the correct profile and height.
Can one make a "mold" for that purpose, out of wood maybe? Just for shaping the kydex?

Get a Styrofoam block and shape it.

Could you use an appropriately sized wooden dowel and form the top to the optimal diameter? And then straight down on the sides?
In my limited use of making first an adjustable cheek riser and an axe sheath, I would say styrofoam as a mold for kydex would be a bad idea. There is high density foam out there that does work if you protect it though.Another idea (which I've yet to work with) is balsa wood.
