A Aimpoint ACRO-cut optic on a Shield RMSc slide: whether it fits, why, and what to buy so the dot seats square.

Will not fitA Aimpoint ACRO-footprint optic will not fit a Shield RMSc slide cut. The enclosed ACRO clamps an ACRO plate; the RMSc is a small open micro cut, an incompatible interface. Use an ACRO-plate slide, or an RMSc micro dot for that slide.

This is the pistol-slide question: your optic is cut for the Aimpoint ACRO footprint, and the slide in front of you is milled for the Shield RMSc pattern. The enclosed ACRO clamps an ACRO plate; the RMSc is a small open micro cut, an incompatible interface.

Match the optic to the cut instead of forcing it. An acro-plate slide, or an rmsc micro dot for that slide keeps the sight seated square so it holds zero under slide cycling.
