Spike's Tactical Flat Top Upper Receiver 9mm – AR-15 Platform

The Spike's Tactical Flat Top Upper Receiver in 9mm is a stripped forged upper designed for building a dedicated 9mm AR-15 pistol caliber carbine. This flat top configuration accepts standard Picatinny-mounted sights and optics, providing a versatile platform for customizing your 9mm build. Machined to Mil-Spec dimensions with a modified ejection port to accommodate 9mm brass, it pairs with Glock or Colt-pattern magazine lowers depending on your bolt carrier group and magazine block setup.

Forged from 7075-T6 aluminum with a black anodized finish, this upper features M4 feed ramps and a standard barrel nut threads (1.125x24 TPI). Does not include barrel, bolt carrier group, charging handle, or handguard. Requires a 9mm-compatible BCG and barrel for completion. Installation requires standard AR-15 armorer's tools and knowledge of pistol caliber carbine builds.
