FN 509 Aimpoint Acro MRD. Made from a black finished aluminum, this durable MRD mount for the Acro P-1 line of mini red dots from Aimpoint is an OEM factory original component from FN America. The mount is designed for the 509 Tactical pistol using the FN Low-Profile Optics Mounting System. Install this mount using the proper plate (501) and screws (515) which are sold separately and do not come with this mount. The mount features the appropriate cuts to securely retain your favorite Aimpoint red dot sight to the slide of the 509 Tactical. FNH small parts are made to the same quality standard that you would find from any other FN firearm or component.

Aimpoint's new Acro P-1 fully-enclosed miniature red dot optic mounts quickly and securely to FN pistols equipped with the patented FN Low-Profile Optics Mounting System. Simply unbolt the two screws securing your slide cap plate to your pistol slide, install the Aimpoint Acro P-1 plate using the same screws and follow the installation steps according to the optic manufacturer's instructions located in their owner's manual.
