Springfield Armory SAINT B5 semi-automatic rifle in 5.56x45mm NATO with a 16″ CMV Melonite barrel, B5 Systems M-LOK handguard and Bravo stock, and one 30‑round Magpul PMAG Gen M3 magazine.
The Springfield Armory SAINT B5 is a purpose-built modern sporting rifle chambered in 5.56x45mm NATO that pairs forged 7075 T6 receivers with B5 Systems furniture for a durable, familiar platform. It ships with a 16″ Chrome Moly Vanadium Melonite-coated barrel and a single 30‑round Magpul PMAG Gen M3 magazine, plus low-profile flip-up iron sights. For an optic under $1,000 that complements this rifle’s role, consider a 1-6x scope such as the Vortex Viper PST Gen II 1-6×24 for fast, practical target acquisition across typical MSR ranges.
Designed for modern sporting rifle (MSR) use and practical range/training applications, the SAINT B5 combines upgraded component choices—like a nickel-boron coated trigger and a Carpenter 158 steel bolt—with a mid-length direct gas system to balance recoil impulse and longevity.
