RS, OPF-S (rear sight, OPF-S) is designed and made for OPF-S, RMR and OPF-S, ACRO adapter plates for Staccato 2011 P, C, C2 and CS.
For the non-Tritium (blacked out) rear sight, use a 5/64 allen wrench to tighten the set screw provided to securely anchor the rear sight in OPF-S, RMR's rear sight dovetail. Torque value: 5 to 7 in lb, do not exceed 10 in lb.
For the tritium rear sight, use a 1.5mm allen wrench to tighten the set screw. Torque value: 5 to 7 in lb, do not exceed 10 in lb.
NOTE:
* As with other dovetailed sights, RS, OPF-S may require fitting. RS, OPF-S is machined from 1018 and not hardened, or black nitrided for this reason.
* OPF-S is compatible with 2011 P's 0.285" front sight, and C2's 0.265" front sight.
* OPF-S is usable with Trijicon's RMR HD, though the sights are very low, below lower 1/4, and nearly unsable with RCR, though the tip of the front and rear sights are visible.
