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.

    The plate is a perfect fit. It is just thick enough to priovide a sturdy Interface while not obscuring my Tru-Glo H3 sights.

    I used this on my G48 MOS with a Holosun 507k. The fit and finish are great and the plate works as advertised. Pretty easy installation and locks down nice and tight with the optic mounted.

    Quick shipping for a great product. The adapter plate for my Glock 43x MOS and Holosun 507k fit snuggly and the supplied screws were exactly what I needed. C&H attention to detail in their craftsmanship shows why they are the industry leader. I appreciated the associated tools offered for red dot maintenance- C&H is my one stop for setting up my newest blaster!

    Plate works great. Installed properly (shorter screw on the correct side) as in the instructions. Took to the range and had failure to eject on every round I shot. Thought might be shield arms mags, switched to factory mags still had the issue. Went home and stripped the gun. Was unable to remove the extractor plunger. Removed the screws from the optic, and plunger fell out. Played with the screws and the screws were too long so they were binding the plunger. Ground down the screws, reinstalled and have had no issues since. Just double check your screws if you have this issue. So other than the screws being too long and wasting ammo, the product is great. Would buy again, was just frustrating.

    I know Glock’s slogan is “perfection”, but their MOS system is NOT. The CH Precision G43x/48 adapter plate achieves what Glock should have built for this platform. Positive, solid lockup between the optic and the gun. I use CH Precision on all my MOS platforms.
