Springfield Saint 5.56mm Semi-Automatic AR-15 Rifle with M-Lok Rail

Overview

The Springfield Saint 5.56mm semi-automatic AR-15 rifle with M-Lok rail represents a precision-engineered entry in the modern sporting rifle category. Manufactured by Springfield Armory, this rifle is built on a forged 7075 T6 aluminum receiver set with a hardcoat anodized finish for corrosion resistance and dimensional stability. The 16-inch CMV (Chrome Moly Vanadium) barrel features a 1:8 twist rate, optimized to stabilize both standard 55-grain and heavier 62- to 77-grain projectiles. The mid-length gas system reduces recoil impulse and improves reliability over carbine-length systems, while the full-length M-Lok free-float handguard provides continuous accessory mounting surfaces without barrel interference. The springfield saint 5.56mm semi-automatic ar-15 rifle with m-lok rail ships with a single 30-round Magpul PMAG magazine and a padded nylon sling.
