NOTE: OPF-G, RMRcc is designed for and compatible with Glock Set 01 compatible slides, not the slim line Glock 43x and 48.
OPF-G, RMRcc (Optics Platform, Forward Controls, RMRcc) is the latest member of the OPF line. OPF-G, RMRcc uses the same proven design of the OPF-G, RMR to keep the RMRcc immobile, the simplest and most effective way to prevent sight to plate mounting screws from loosening and shearing.
RMRcc has its own footprint. Gone are the two lug holes in front, these are replaced by two larger diameter threaded posts (bosses) through which the sight to mount/plate screws are installed. The sight to mount/plate screws are also significantly strengthened, though with the OPF-G, RMRcc design that holds the sight immobile on the plate, the larger diameter and stronger screws aren't as important, we always welcome screws that are less likely to strip.
RMRcc's smaller footprint (same length, but narrower and shorter than the RMR) means the sight no longer overhangs the slide. For those that conceal carry a full sized Glock, we believe they'll come to appreciate the reduction in width, we like it a lot more than we thought we would.
OPF-G, RMRcc ships with a T10 wrench, 2 plate to slide screws (M3-0.5mm x 6mm), 2 sight to plate screws (T10 5-40 x 1/4 ), and a packet of VC-3. The RMRcc mounting screws that ship with the RMRcc can also be used with OPF-G, RMRcc.
