C&H Precision Weapons Staccato Duo Adap 407K/507K
$142.95
The C&H Precision Weapons Staccato Duo adapter for Holosun 407K/507K red dot sights gives you a rock-solid optic mount purpose-built for the Staccato Duo platform. If you're running a modern, compact pistol and want to co-witness a quality reflex sight without compromise, this precision adapter delivers the fit and durability you expect from a machined component engineered by an American manufacturer focused on tight tolerances and long-term reliability.
C&H Precision manufactures each adapter on HAAS CNC equipment in Coastal Georgia, holding dimensions to demanding tolerances that ensure your optic sits true and stays put through training, competition, or duty use. The 6061 aluminum body is finished in MIL-SPEC Type III hard anodize—a military-grade protective coat that resists corrosion and handling wear. What sets this adapter apart is the stainless steel T-nut design, which provides six to seven threads of engagement for secure hardware clamping and the ability to replace individual fasteners if needed, without ditching the whole plate.
The Holosun 407K and 507K are compact, proven optics, and this adapter is engineered to position them correctly on your Staccato Duo. Every plate undergoes multiple quality checks before shipment, so you're getting a component backed by real manufacturing discipline and customer support from a small, accountable shop—not a dropshipped generic part.

Frequently Asked Questions
Will this adapter work with my Staccato Duo and Holosun 407K/507K?
Yes—this adapter is specifically designed to mount Holosun 407K and 507K red dot sights on the Staccato Duo slide. The adapter is precision-machined to ensure proper optic seating and alignment on that platform.
What if I damage or lose a screw?
The mounting hardware is replaceable. Rather than needing a new plate, you can order replacement 416 stainless steel fasteners and T-posts. C&H designed the system so individual components can be swapped without discarding the whole adapter.
Why does the anodize finish matter?
MIL-SPEC Type III hard anodize is a military-grade protective coating that's thicker and tougher than standard anodize. It resists corrosion from moisture and handling, and it won't wear or flake easily—important for a component that sits on a firearm you actually use.
Is this made in the U.S.?
Yes. C&H Precision Weapons manufactures all adapters in-house on CNC equipment in Coastal Georgia. Every plate undergoes multiple quality checks before shipment, so you're getting a domestic-made component from a family-owned shop with direct accountability.
