Precision-machined billet aluminum upper receiver for AR15 builds. Guntec's slabside design offers a clean, modern aesthetic with full compatibility for standard AR15 components.
Fits: AR15
The Guntec slabside upper receiver represents a modern approach to AR15 construction. Machined from solid billet aluminum, this upper delivers the precision and durability serious builders demand.
This is a stripped upper receiver only. You'll need to source a bolt carrier group, charging handle, and handguard separately to complete your build.
Guntec focuses on precision manufacturing and clean aesthetics. The slabside design appeals to builders who prefer a streamlined look and want complete control over their build specifications.
Whether you're assembling a precision rifle, a lightweight carbine, or a specialized build, this upper receiver provides the foundation for a quality AR15.
