Description
Upgrade your build with a rugged forged AR-15 upper receiver engineered for precision and reliability. Our forged uppers are designed to pair perfectly with forged lowers and deliver the strength and dimensional consistency shooters expect. The inner thermal-fit dimension is held to .997″ -0.0 / +0.001″, which is intentionally tight — the receiver is designed to be heated (more than a small hair dryer) and then fitted to the M4-pattern barrel extension for a repeatable, secure press fit that resists movement under sustained firing.
Each assembled upper arrives ready-to-complete: the ejection port cover (dust cover) and forward assist are pre-installed to save time at the bench. Every unit is made in the USA on American-made machines and inspected for fit and finish. Because press-fitting barrels and headspacing are critical to safe, reliable operation, Dirty Bird USA recommends professional gunsmith installation for all barrel and receiver mating — we cannot warranty hardware damaged by improper installation. Buy your forged upper receiver from Dirty Bird USA and build with confidence.
