The Saint Edge ATC AR-15 .223 Wylde is built around the patented “Accurized Tactical Chassis” and is designed to deliver maximum precision in the AR platform. Featuring a monolithic lower/handguard system, the SAINT Edge ATC delivers a 100% free-floated barrel ensuring that the barrel, barrel nut and gas system are totally free from any contact with the lower chassis.

The result is a .223 Wylde rifle that delivers guaranteed sub-MOA performance for three shots with a skilled shooter and match-grade ammunition.

The SAINT Edge ATC features a low-key, yet ruggedly durable black finish of Type III hardcoat anodizing and Melonite.

The proprietary Springfield Armory® Flat Modular Match Trigger reflects the state of the art in tack-driving fire control systems.

The SAINT Edge ATC is designed to deliver maximum accuracy out of the AR-15 platform. Accordingly, Springfield Armory stands behind all SAINT Edge ATC rifles with a rock-solid sub-moa accuracy guarantee — for a three-shot group at 100 yards with quality match-grade factory ammunition, in the hands of a skilled shooter.
