Discontinued: SAINT® Edge ATC AR-15 Rifles

Discontinued: SAINT® Edge ATC AR-15 Rifles

The all new SAINT Edge ATC 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.

Chambered in .223 Wylde, the SAINT Edge ATC is offered in a standard black model as well as an Elite version finished in Cerakote® Coyote Brown, paired with an upgraded LaRue 2-Stage trigger and B5 Systems’ Precision Stock. For those that demand sub-moa precision from their AR-style rifle, the SAINT Edge ATC series is guaranteed to deliver.​


The heart of the SAINT® Edge ATC system is the patented Accurized Tactical Chassis monolithic lower. Machined from 6061 T6 aluminum, the lower receiver is designed to remove any contact with the barrel, barrel nut and gas system. This completely free-floated system is the foundation of the SAINT Edge ATC’s unparalleled accuracy.

The SAINT® Edge ATC features an 18” barrel in .223 Wylde manufactured by Ballistic Advantage, giving the rifle a high-performance precision barrel for maximum accuracy. Featuring a 1:7” rate of twist and a rugged Melonite® coating, the 18” barrel delivers impressive ballistics and amazing downrange performance.

  • M16 BCG

    Overbuilt and designed for long life and rugged use, the bolt carrier group has been shot peened and MPI tested for reliability.

  • SA Muzzle Brake

    Topping off the muzzle of the 18” Ballistic Advantage barrel is an SA Muzzle Brake, designed to offer maximum reduction in perceived recoil.

  • B5 Systems Grip

    The composite B5 Systems pistol grip delivers enhanced ergonomics through its steep angle, extended tang and palm-filling design.

  • 20-Round PMAG

    A short 20-round PMAG is included to offer a good balance between on-board firepower and the ability to easily shoot from the bench.

  • B5 Systems Stock

    The SAINT Edge ATC features a premier B5 Systems SOPMOD stock or Precision stock on the elite model for further adjustability.

  • Accu-Tite Plus

    The Accu-Tite™ Plus tension system utilizes two conical set screws to eliminate any play between the upper and lower receiver for optimized accuracy.


Offering maximum performance as well as flexibility, the .223 Wylde chambering of the SAINT® Edge ATC offers the best of both worlds. Capable of firing both .223 and 5.56 NATO rounds, the .223 Wylde chamber features a chamber throat that is tight enough to wring the most performance out of .223 Match ammo, yet still safely fire 5.56 NATO rounds.


The SAINT® Edge ATC Elite takes performance to the next level. Featuring all the advantages of the Accurized Tactical Chassis system, the Elite variant adds a fully adjustable B5 Systems Precision Stock, LaRue Tactical MBT Flat Two-Stage Trigger and a Cerakote® Coyote Brown finish.


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.
