DRY-FITTING DISCLAIMER:
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.
IRON SIGHTS DISCLAIMER:
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.

Great product perfect fit for the sig xten great quality I would yes if your going to buy plate make sure to get the replacement screw kit because the screws that come the holosun red dot sights don’t fit the sig slide

Item arrived sooner than expected and fit my P320 perfect. The Holosun 508T mounted easily and the supplied screws from CHPWS were a perfect fit. Great product from a superior company.

Wow! Fantastic service and quick action to ship! This adapter fit my P320 XTEN like a glove! I used the two C&H (green highlighted) screws (the smaller ones) that came with the plate and the Holsun507C is bang on! I’ve shot 300 rounds and it is a beast of a mounting system! I highly recommend their products! V/R Charles

It works! A thin peice of metal that wedges my rmr in place with a few holes. I just wish it wasn’t $60 seems a little much but I appreciate the part.
