The Sig Sauer MCX/MPX polymer black skeletonized cheek riser is a drop-in upgrade for shooters running Sig's factory skeletonized stock on either platform. If you've found that your cheek weld sits too low on the skeletal stock—especially when mounting optics or running suppressed—this riser brings your face back into proper alignment with your sighting system. It's a straightforward, no-gunsmith fix that costs far less than swapping stocks entirely.
Molded from durable polymer, the riser is built to handle the recoil of rifle-caliber MCX or 9mm MPX fire without degradation. The black finish matches your skeletonized stock and keeps aesthetics clean. Installation is quick: the riser locks into place on the factory stock using the included locking insert, and there's nothing permanent about it—you can remove it anytime if your setup changes.
Whether you're running a red dot, LPVO, or traditional scope on your MCX or MPX, proper cheek-to-stock contact matters for consistent sight picture and follow-up shot control. This riser is purpose-built for Sig's proprietary skeletonized design, so fitment is guaranteed.
