C&H Precision Weapons Rmr Adapter To Holo 407K/507K

The C&H Precision Weapons RMR Adapter for Holosun 407K/507K Red Dot Sights is a precision-engineered mounting plate that lets you run a Holosun 407K or 507K on firearms and slides cut for the Trijicon RMR footprint. If you've got an RMR-pattern mount already in place—on a pistol slide, AR upper, or other platform—this adapter bridges the gap, letting you use one of Holosun's compact, proven red dots without a new cut or full re-work. It's a straightforward, practical solution for shooters who want to swap optics or standardize across different guns.

C&H Precision Weapons manufactures this adapter at their Georgia facility, holding each piece to tight tolerances on CNC equipment and running multiple quality checks before it ships. The plate is machined from 6061 aluminum and pairs with stainless steel hardware, keeping weight minimal while maintaining rigidity and corrosion resistance. If you're building a carry gun, competition setup, or duty platform and want to preserve an existing RMR cut while running Holosun glass, this adapter removes the guesswork.

Made in the USA, this adapter is a no-nonsense piece of kit—the kind of mid-level solution that makes sense when you're trying to avoid a slide re-cut or replace an RMR without a full teardown. Fits the 407K and 507K, both respected compact open-emitter designs. Check your existing RMR footprint and your Holosun model before ordering to make sure the fit is right for your platform.

Frequently Asked Questions

Will this adapter fit my Holosun 407K or 507K?

Yes—this adapter is designed specifically to mount Holosun 407K and 507K red dots onto platforms that use the Trijicon RMR footprint.

What's the difference between this adapter and just cutting a new slide?

This adapter lets you use an existing RMR-pattern cut without re-machining your slide or firearm. If you already have an RMR footprint, the adapter bridges to your Holosun optic; if you need a new cut, that's a gunsmith job. This adapter is the faster, cheaper alternative.

What material is the adapter made from?

The plate is machined from 6061 aluminum, paired with stainless steel mounting hardware. This combination keeps weight low while resisting corrosion and maintaining rigidity.

Is this made in the USA?

Yes. C&H Precision Weapons manufactures, machines, and quality-checks each adapter at their facility in Georgia.
