Designed and made in the USA, the Forward Controls Design OPF-G, ACRO plate is designed for the GLOCK MOS system to mount Aimpoint’s ACRO P1 and P2 on the slide. This Glock 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 covered in Melonite to increase the ability to avoid corrosion and to increase the lifetime of the mounting plate.
