Springfield STEQ975556BX: The Saint Edge Evac features an enhanced nickel boron coated single stage trigger allows for a crisp, clean trigger press with zero creep. Its lightweight design is engineered for improved accuracy, reliability, and consistent performance comparable to custom AR builds often costing much more. The sleek, patent-pending free-float handguard is slim and M-Lok compatible for accessories. Underneath, a pinned, mid-length, adjustable gas block aids in flawless feeding and ejection. To aid in accuracy, the 7.50\" barrel, CMV Melonite finished inside and out, has an optimum 1:8 twist, unique muzzle brake, flip-up dual aperture rear sights, and an adjustable front sight that flips down for use with optics.
