At C&H Precision, our products are designed and manufactured to meet tight tolerances. Installation can be affected by variations in your plate, hardware, optic, and firearm tolerances. For safe installation and to prevent potential damage to any component, we advise dry-fitting all parts before a full installation. If any problems arise during this process, please reach out to our Customer Service via our contact portal.
When making aftermarket firearm modifications, factory components can often become obsolete, particularly when mounting optics on the slide, whether through direct milling or using a plate. Achieving the correct height for low co-witness iron sights depends on factors such as the firearm type, mounting plate, optic, and slide cut. For assistance in determining the appropriate iron sight height for your specific setup, please contact our Customer Service team through our dedicated contact portal.

    Honestly a miss IMO. $90 I wont get back. Purchased for a g48 MOS. Tried 3 individual optics and all of them came loose and lost zero within 10 rounds. All loctited (cleaned before reinstalling), waited to dry, then fired to build a zero. I’m not an engineer by trade, but I think it would be better suited to thread the actual plate itself (its wicked thick) as opposed to the small female nuts that receive the optic mounting screws. Every mounted optic already has 2 potential points of failure (2 mounting screws) and this plate adds an additional Two points of failure in the form of tiny, fine threaded bolts that fit through the optic, through the bottom of the plate and fasten into little rectangular nuts that just kind of sit in there? Ended up just cutting my losses and going back to an RMRcc footprint optic. Definitely wouldn’t trust this on anything past a range toy. All the other CH plates I own are solid.

    Just received this plate in for my Glock 43X MOS and it fits perfectly and steadily mounts the Holosun 507C. Very well made and looks to be very strong. I thought it would be a thinner but it works just fine, I was also worried about the screw length for placing the adapter on the slide as I have heard many people who have the 507K without the plates stating that the screws interfere with the EXTRACTOR DEPRESSOR PLUNGER & SPRING ASSEMBLY but the screws fit perfectly and do NOT interfere with the EXTRACTOR DEPRESSOR PLUNGER & SPRING ASSEMBLY at all. Thanks for making a great product.
