Echelon Night Sights 4.5"
Springfield Armory 
Overview
Engineered with superior ergonomics and built to withstand the harshest conditions, the Echelon™ 4.5" 9mm handgun sets a new standard for modern, striker-fired duty pistols. With a host of patent pending features, this modular pistol is designed around a robust stainless steel chassis. In addition, a revolutionary optics mounting system allows for unparalleled adaptability with a broad range of optics. Fully ambidextrous, the Echelon features a 3 dot trittium sight system for fast target acquisition in low light conditions.
The Echelon pistol is built around a new Central Operating Group (COG). The COG is a self-contained unit that houses the fire control group, slide stop, and magazine release. It is serialized and can be easily moved between different grip modules. This allows users to customize the feel and ergonomics of their Echelon pistol to their specific needs.
The Echelon also features a patent-pending optic mounting system called the Variable Interface System (VIS). The VIS allows users to mount over 30 different optics directly to the slide without the use of adapter plates. Simply configure the self-locking pins for the footprint of your desired optic to achieve a low, direct mount for improved sight picture and intuitive alignment.
