Guntec USA AR-15 Slabside Billet Flat Top Stripped Upper Receiver Black

The Guntec USA AR-15 Slabside is a stripped billet flat-top upper receiver machined from T6 6061 billet aluminum and finished in a hard-coat anodized black. Featuring a distinctive slabside profile, this upper is designed as a stripped component — no barrel, handguard, bolt carrier group, or charging handle are included. The flat-top Picatinny rail allows direct mounting of optics or iron sights. Compatible with standard mil-spec AR-15 lower receivers. Intended for custom builds requiring a billet aesthetic over a traditional forged upper.
