OPF-FNT09T, ACRO is a one piece, billet machined plate for Aimpoint P1/P2, and Steiner MPS, it is not guaranteed to work with cheap Chinese copies that have the ACRO footprint.
OPF-FN509T, ACRO is shipped with a packet of VC-3, 6-40 x 3/8 with 5/64 Allen drive screws, FN supplied 6-40 x 5/8 T10 screws can also be used.
A proper torque wrench is required to impart the correct torque value to the mounting screws.
For plate to slide screws, the pistol's optics plate covers screws can be used. We supply 6-40 x 3/8 Allen head screws (5/64 Allen bit). FN 509's optics plate covers screws can also be used.
