Looking for a top quality Upper Receiver at wholesale prices? The NBS AR-15 Assembled Upper is machined by one of the foremost manufacturers of mil-spec AR-15 components in America. Normally these assembled uppers are only available to builders when purchased from a name brand at a substantial markup, but we’re making these available at wholesale prices.
What makes this upper different from other “Mil-Spec” upper receivers?
- Machined from top tier forgings.
- Shot blasted prior to anodizing which results in a finish which is more consistent, durable and uniform. No chalky or purplish anodizing.
- Slightly chamfered lug holes for quick and easy takedown/pivot pin engagement.
- Quality assurance program that exceeds industry standards.
Features:
- 7075-T6 Forged Aluminum
- Black Anodized finish
- Flat-Top
- Mil-Spec dimensions for guaranteed fit with any mil-spec lower receiver
- Mil-Spec Forward Assist sourced from a top-tier supplier of the Military and OEM Manufacturers
- Mil-Spec Dust Cover sourced from a top-tier supplier of the Military and OEM Manufacturers
- M4 Feed Ramps
