Designed and made in the USA, the Forward Controls Design OPF-M17, ACRO plate is designed for the M17/M18 and SIG P320 pistols to mount Aimpoint’s ACRO red dot sight on the slide. This P320 compatible mounting plate is designed to fully support the optic in the front and rear with threaded posts that connect with the sight-to-mount screws, ensuring minimal sight movement. The adapter plate is made of 4140 steel and black oxide coated to increase the ability to avoid corrosion and to increase the lifetime of the mounting plate. 

Please note: This plate is not compatible with P320 Pro Cut, P320 sub compact, AXG, and RX. Also, Steiner MPS optics may require additional tapping to seat correctly. Manufacturer recommends holding LCI (loaded chamber indicator) with your finger or a piece of tape while removing the plate from the slide to avoid damaging it.
