This guide details the process of mounting a red dot optic to a Sig M17/M18 slide using a CH Precision adapter plate. The CH Precision SGX-RSH-GDT adapter converts the factory DeltaPoint Pro footprint to an RMR footprint, allowing for a wider range of optic compatibility. The installation involves careful seating of the adapter plate, securing it with Loctite and specific torque settings, and then mounting the chosen red dot optic with its own set of screws and torque specifications. The adapter also offers an option for a Glock dovetail rear sight.

Quick Summary

To mount an RMR footprint red dot on a Sig M17/M18, use a CH Precision adapter plate (SKU SGX-RSH-GDT) that converts the DeltaPoint Pro footprint. Clean threads, apply Loctite Blue 242, and torque the adapter plate to 10-15 inch-pounds, then torque the optic to 10-12 inch-pounds using a torque screwdriver.

Frequently Asked Questions

What adapter is needed to mount an RMR footprint red dot on a Sig M17?

To mount an RMR footprint red dot on a Sig M17 or M18, you need an adapter plate that converts the factory DeltaPoint Pro footprint. The CH Precision SGX-RSH-GDT is a popular option for this conversion, allowing compatibility with optics like the CH Optics EDC XL or Holosun 407C/507C.

What are the recommended torque settings for mounting a red dot optic on a Sig M17?

When mounting a red dot optic to a Sig M17 using an adapter plate, it's crucial to use a torque screwdriver. For the optic mounting screws, a torque of 10-12 inch-pounds is generally recommended. Always consult the optic and adapter manufacturer's specifications for precise torque values.

Does the CH Precision adapter for Sig M17 allow for iron sights?

Yes, the CH Precision adapter plate (SKU SGX-RSH-GDT) for the Sig M17/M18 is designed with a slot that accommodates a Glock dovetail rear sight. This allows for the co-witnessing of iron sights, which can be particularly useful with suppressor-height sights.

What type of Loctite should be used for mounting a red dot optic?

For mounting red dot optics and adapter plates to firearms, Loctite Threadlocker Blue 242 is recommended. This provides a medium-strength bond that prevents screws from loosening due to recoil and vibration, while still allowing for disassembly with standard tools.
