Springfield Armory SAINT AR-15 Features

This is the Springfield Amory SAINT® AR-15 Rifle for the rugged individualist who appreciates the classics. The lightweight mid-length direct gas impingement operating system offers superlative reliability. You can customize your AR 15 SAINT to fit your unique personality. Top-end Bravo Company furniture combines comfort with ample M-Lok® space.

The traditional front sight base is both unbreakable and foolproof. A 16" chrome moly vanadium Melonite-coated 1:8"-twist barrel strikes the perfect balance between compact portability and rugged performance.


The traditional Mil-Spec front sight base features a square-profile A2 front sight and is a proven design.


The included flip-up rear sight runs perfectly all the time, independent of batteries.


M-Lok® compatible Bravo Company handguards combine modest weight, minimal bulk, and maximum versatility.

SAINT® firearms are offered in several caliber options. Locate the cartridge designation, for caliber, marked on the firearm’s barrel. This information indicates the correct ammunition that must be used in your firearm. May be visible under forend on some models. 

SAINT firearms rely on the amount of pressure of the gassed developed when the cartridge is fired. This is because SAINT firearms are direct impingement gas operated firearms. SAINT firearms chambered in .300AAC Blackout are designed to operate with both subsonic and supersonic ammunition under the proper conditions.

Supersonic ammunition will operate equally well when fired with or without a sound suppressor. Most subsonic ammunition is designed to be fired suppressed. Subsonic ammunition may not function reliably in semi-auto firearms without a sound suppressor. 

The SAINT is designed to reliably function with subsonic ammunition when a sound suppressor is attached. Firing subsonic ammunition without a sound suppressor may not reliably function in the SAINT. NOTE: If your SAINT® rifle/pistol is chambered in 5.56 NATO, it will fire both 5.56 NATO and .223 Remington ammunition.
