(Excuse my budget optic.)
Work finally slowed down enough for me to squeeze a personal project in, so I took the chance to make a cheek riser for my APC223. I made a pair of them, different heights, for what I thought would be the necessary rise for the low folder. (The taller one worked better.) The APC223, being a piston gun, has quite a jump in height-over-bore (1/2"+) over an AR, plus the comb on the APC is lower, relative to the bore, compared to an AR.
I was originally going to make the riser like the SAN one, and connect the riser to the hump near the hinge, but I didn't want to get bogged down in details when I didn't know all the specifics of the required tooling, measurements, the method it would mount, or how I would manufacture it. I went the easier route and profiled a no-snag, ramped style. It's a little short for a traditional, bladed rifle posture; squared up, sitting, and prone seem to be all right.
These ones are made of acetal copolymer, which is what I had on hand. What I had immediately available influenced a lot of the design decisions in this iteration. I think glass-filled nylon would be better, and I'd do a couple of things differently underneath with the mounting, ribs, and whatnot.
It snaps into place and doesn't budge, which I'm happy about.
And you can still fold it.
The bad news, for anyone who might want one, is I don't have any plans to make more of these (or other iterations) at the moment. A reason why is it'd be expensive to sell. Volume is too low to justify injection molding. Glass-filled nylon costs 4-5x as much. I'd need one or two custom tools for milling a more SAN-like profile and reducing cycle time. Plus, I would have to re-program my spaghetti code, and make a fixture, to be more suited for production. But never say never. If the summer work load is low enough, it might happen, provided the interest is there.
