Springfield Saint Edge ATC | .223 Wylde | 18″ STA918223B

The SAINT Edge ATC by Springfield Armory is a chassis-style AR built for precision in the AR platform. It uses a monolithic Accurized Tactical Chassis to fully free-float the barrel and isolate the gas system from the lower, with component choices aimed at match-oriented accuracy and repeatable performance. This configuration is well-suited to precision range work and competition shooting. For a quality optic under $1,000 that pairs with this rifle, consider a low-power variable optic such as the Vortex Viper PST 1-6×24 for fast target acquisition and precise engagements.
