In stock
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.

What makes this upper different from other “Mil-Spec” upper receivers?
- Machined from top tier forgings.

- 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

- 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

Hey a completed upper, good price, could not buy the parts and assemble it for the same, **** product, works fine. I recommend it having done some 30 ARs
USNBS AR-15 Upper Receiver
This NBS upper receiver is No BS! The fit and finish is awesome. Matched perfectly to my barrel and lower.
USExcellent upper for the price
Every bit as good as the "name brand" uppers and much less expensive.
USFitnFinish1
Product is well worth the money, barrel sat flush with feed ramps and this upper is a slightly tighter fit to my lower than my other budget upper. Needless to say can't wait to get it painted and all put together. Service was seamless and shipping was fast. Will definitely come here first for my next build.
