7. Place the MRD plate in the MRD plate cut, sandwiching the o-ring
between the slide and plate (Figure 70).
8. Set the optic or slide cap on top
of the slide and MRD Plate. If
your optic requires an MRD insert
to be installed under the sight, it
should be installed at this time
(Figure 71 & 72).
9. Start both mounting screws and
tighten them down clock-wise
with finger pressure with the
provided T10 Torx wrench.
NOTE: Do not use threadlocker. The
fastening system used on the FN
Optics Mounting System is self-
locking and does not require
threadlocker to remain tight when in
use. Use of a thread locker may
make it difficult or impossible to
remove the optic or slide cap
without damage to the components.
