Springfield Saint 5.56 NATO AR-15 Rifle with B5 Furniture

Overview

The Springfield Saint 5.56 NATO AR-15 Rifle with B5 Furniture is a direct descendant of Springfield Armory’s proven Saint platform, engineered for reliability out of the box. Chambered in 5.56 NATO, this rifle combines a forged 7075 T6 aluminum upper and lower receiver with a 16-inch chrome-moly vanadium barrel featuring a 1:8 twist rate. The B5 Systems furniture set—including the pistol grip, stock, and handguard—provides durable, ergonomic control without added weight. Each rifle is test-fired and verified at the factory, so you get a ready-to-run carbine that meets mil-spec tolerances.
