A Aimpoint ACRO-cut optic on a Trijicon RMR 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 Trijicon RMR slide cut. The ACRO clamps a closed body onto an ACRO plate; an RMR slide is an open screw-down cut, a different interface entirely. Use an ACRO-plate slide or an ACRO Picatinny plate.

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 Trijicon RMR pattern. The ACRO clamps a closed body onto an ACRO plate; an RMR slide is an open screw-down cut, a different interface entirely.

Match the optic to the cut instead of forcing it. An acro-plate slide or an acro picatinny plate keeps the sight seated square so it holds zero under slide cycling.
