Springfield Armory SAINT ST916556BLC-B5 5.56 NATO 16" Rifle

The Springfield Armory SAINT ST916556BLC-B5 delivers proven AR-15 platform reliability with enhanced ergonomics and modern manufacturing standards. This 5.56x45mm NATO rifle combines traditional direct impingement operation with contemporary features that serious shooters demand.

What Makes This Different

The SAINT platform distinguishes itself through Springfield's proprietary Melonite barrel treatment, which provides superior corrosion resistance and bore longevity compared to standard chrome-lined barrels. The B5 Systems Bravo stock offers six-position adjustment with enhanced cheek weld consistency, while the M-LOK handguard eliminates the weight and bulk of traditional quad rails. Springfield's quality control standards ensure each rifle meets military specification tolerances.

Key Features

• 16-inch Melonite-treated barrel with 1:8 twist rate for optimal bullet stabilization
• B5 Systems Bravo adjustable stock with improved length of pull options
• Free-floating M-LOK handguard for accessory mounting flexibility
• Hard coat anodized upper and lower receivers meeting mil-spec standards
• Single-stage trigger with consistent 6-7 pound pull weight
• A2-style flash hider and standard carbine buffer system
• Ships with one 30-round magazine (where legally permitted)

Field performance centers on the rifle's 1.5-2 MOA accuracy potential with quality ammunition. The 16-inch barrel length provides full powder burn for 5.56 NATO cartridges while maintaining maneuverability for tactical applications. The Melonite finish resists fouling buildup and simplifies maintenance during extended shooting sessions. Law enforcement agencies and competitive shooters appreciate the consistent lockup and reliable cycling across various ammunition weights.
