The Spikes Tactical 9mm Flat-Top AR-15 Upper (brand part no. SFT902D) is a stripped upper receiver machined specifically for the 9mm AR-platform, giving builders a dedicated pistol-caliber receiver to finish out with their own barrel, bolt carrier group, and handguard. Machined from 7075-T6 aluminum and finished in a durable black hardcoat anodizing, it holds to the same tight tolerances Spikes Tactical runs across its receiver lineup. The flat-top profile gives you a full-length Picatinny rail for mounting an optic exactly where you want it, and the receiver is machined to accept a 9mm-specific bolt carrier group and magazine well insert rather than a standard 5.56 setup. It is a solid foundation for a home-defense or range-ready 9mm AR build.
