Does the Holosun 509T fit the Springfield Armory Echelon?

No: the slide is not cut for the Holosun 509T footprint, and no plate listed here bridges it.

No known fit

Enclosed emitter

Nothing in this database bridges the Springfield Echelon VIS interface to the Holosun 509T pattern. Its own world. Almost always mounted on a dedicated 509T plate; steel plates are the common recommendation. A custom plate or a re-mill would be the only route — check with a plate maker before assuming it can't be done.

How this slide mounts an opticInstead of plates, three sets of self-locking pins drop into the slide to recreate a footprint's lug pattern. Pin set 1 (fitted from the factory) gives RMR, set 2 gives DeltaPoint Pro, set 3 gives Shield. The optic then bolts straight to the slide, so nothing stacks. ACRO and Docter optics still need an adapter.
