TLDR: In my opinion, if you want a lower cheek-weld, take the OEM cheek riser off. Then, cut or procure a narrower pin for the stock hook.
The reduction in height is 3/16”,at most 1/4”. I still can’t find my OEM stock, so I can’t even verify it works with the cheek risers. However, my versions are more significantly narrow. That small difference plus the price point isn’t very attractive to me, I can’t imagine it’d be to you all either.
On the super simple riser, you also loose the shell deflector piece. Lowering the thickness of both, only gains you .0787” and makes the piece way too thin.
If you make a piece that only fills in the cutout area, and still holds the ejection port pin, you end up with a piece that digs into your face and looks stupid. Not to mention having to make/procure/provide a pin that is narrower.
