Description

The Spikes ST-15 Enhanced Complete Upper is a mil-spec upper receiver assembly for the 5.56x45mm NATO AR-15 platform. It pairs a 16″ mid-length cold hammer forged barrel with a 1:7″ twist and a black phosphate finish, giving shooters a duty-grade foundation for a new build or a precision-driven replacement for a worn upper.

The 7075-T6 aluminum upper receiver wears a black finish and ships optic ready, with no iron sights installed so the end user can configure their preferred optic or co-witness setup. The included 12″ SAR3 free-floating handguard provides a rigid, lightweight platform that does not contact the barrel, helping the cold hammer forged bore maintain its accuracy shot after shot.

Designed as a direct replacement upper for any mil-spec AR-15 lower, the ST-15 Enhanced line is built to the same standards Spikes Tactical supplies to law enforcement customers. The mid-length gas system smooths out the recoil impulse and reduces felt wear compared to carbine-length setups, making this upper a strong fit for defensive, patrol, and recreational range use.
