Also known as: M4E1 Spartan, Aero M4E1 Spartan Complete Rifle
Overview
The Aero Precision M4E1 Spartan is a value-oriented AR-15-pattern semi-automatic carbine chambered in 5.56x45mm NATO. It pairs Aero's M4E1 enhanced one-piece upper receiver and 15-inch Enhanced M-LOK Gen 2 free-float handguard with a 16-inch chrome-moly-vanadium barrel and mid-length gas system. Offered as a complete rifle with Magpul CTR stock and MOE grip, the Spartan line brings Aero's builder-grade receiver set to a lower price point, typically dressed in a distressed Cerakote finish.
