Upgrade your Springfield Armory Echelon with the Complete Pin Set for the Variable Interface System. Designed to help secure compatible optics with a precise, stable fit, this pin set supports the Echelon's patent-pending mounting system by applying lateral pressure as the mounting screws are tightened to spec. The result is a cleaner, tighter interface that helps reduce left and right movement for dependable optic alignment.

This complete set includes Pin Set 1, Pin Set 2, and Pin Set 3, giving you the hardware needed for a wide range of compatible footprints. It is intended for use with the Echelon Variable Interface System and compatible optics such as Trijicon RMR, Leupold DeltaPoint Pro, Shield RMSc, Holosun, EOTECH, and more. Whether you are setting up a new optic or refreshing your mounting hardware, this set helps deliver a secure connection between slide and optic for confident performance.

Manufacturer-supplied screws may require modification for proper fit.
