Springfield Saint 5.56NATO 16" Barrel 30+1 (Vault)

The Springfield Armory Saint Vault is a representative/sample trade-show display firearm. The Springfield Saint is a high-performance AR-15–style rifle chambered in .223 Remington and 5.56 NATO, featuring a 30-round magazine capacity. Its 16" chrome moly vanadium barrel is Melonite-coated for durability, threaded 1/2x28 for suppressor compatibility, and paired with an adjustable overall length of 33" to 36.25". A rugged Black Melonite finish ensures excellent corrosion resistance. Outfitted with Bravo Company furniture, the rifle offers enhanced comfort and modularity, while an A2 front sight and low-profile flip-up rear sight provide precise, dependable target acquisition—ideal for tactical use, home defense, or range work.

Built for reliability, the Saint employs a lightweight mid-length direct-impingement gas system tuned for consistent performance and reduced recoil. Its traditional, fixed front sight base offers durability and no-nonsense dependability. The 16" barrel’s 1:8" twist supports a broad range of bullet weights, delivering tight groups and stable accuracy. Bravo Company accessories—including the Gunfighter stock and grip—enhance ergonomics and support the addition of lights, lasers, or optics through the integrated M-Lok handguard. Blending classic AR design with modern refinement, the Springfield Saint Vault model provides a versatile, reliable platform ready for customization.

Its durable materials, precise barrel construction, and user-focused ergonomics make it a strong option for shooters seeking a lightweight, adaptable AR to add to their collection. Backed by Springfield Armory’s reputation for craftsmanship, the Saint delivers the performance, durability, and flexibility demanded by today’s shooters.
