The Viridian OPMOD Omega Compact Green Dot Reflex Sight is compatible with the Springfield Echelon. However, this is a micro-optic while the Echelon will accept full size optics. Using a larger optic, you will get benefits of a bigger window and using the entirety of your optic cut. Because the Echelon uses a universal mounting system, you can mount essentially any optic. If you want to use a Viridian optic, I recommend their full size offerings such as the RFX-35 and Omega, both can be found linked below:
