About this product

The Springfield Armory SAINT Edge ATC is built around the patented Accurized Tactical Chassis (ATC) and a monolithic lower/handguard that provides a fully free-floated barrel for repeatable accuracy. The platform is intended to deliver precision performance from an AR-style chassis with match-oriented components and a heavy-duty feature set. The design emphasizes consistent barrel harmonics, a robust receiver interface, and match-grade componentry for disciplined shooters. The factory specification includes a Ballistic Advantage Melonite-treated 18″ barrel and a B5 Systems-enhanced SOPMOD stock for a balance of stability and modularity.
