The C&H Precision Weapons SA Echelon adapter for 407K/507K/C&H EDC lets you mount a Holosun optic to your Springfield Armory Echelon slide without guesswork or gunsmithing. If you've standardized on Holosun's compact red dot ecosystem but carry an Echelon, this adapter bridges that gap with the kind of precision fit that keeps your zero solid through carry and range work alike.
Built from 6061 aluminum and finished in Mil-Spec Type III hard anodize, this plate handles the durability demands of a duty or carry gun. C&H machines every adapter on HAAS CNC equipment and runs multiple quality checks before it ships—the kind of attention that matters when your optic mount is a direct line between your slide and sight picture.
Stainless steel hardware is included, so you're ready to install out of the box. Whether you're building a carry gun, a nightstand Echelon, or a range toy, this adapter gives you access to the Holosun 407K or 507K without compromise.
