The BAD 16" upper receiver in Elite 556 AMBI configuration is a complete, ready-to-run upper assembly built around a billet 7075-T6 aircraft-grade aluminum receiver. It's designed for shooters who want quality machining, genuine ambidextrous controls, and the flexibility to configure an AR-15 platform rifle without compromise. Whether you're building a precision rifle, a practical duty gun, or an all-around carbine, this upper delivers the foundation you need with attention to detail that shows in every component.
The receiver itself is milled from high-spec aluminum and finished in Cerakote Black, combining durability with a professional appearance. Integral to the design are ambidextrous controls—your charging handle and all operating surfaces work equally well for left or right-handed shooters. The free-float M-LOK handguard keeps the barrel isolated from chassis flex, a feature that matters when you're chasing accuracy or reliability under stress. Mounting points at 3, 6, and 9 o'clock positions give you clean, tactical placement for lights, lasers, and grips; a full-length Picatinny rail runs the top, marked with BAD's signature notch for a clean, integrated look.
The 16-inch barrel is 4150 chrome-moly steel with black nitride finish—a proven pairing for both longevity and shot-to-shot consistency. Each barrel ships individually head-spaced to a matching 9310 steel bolt, so your function and reliability are dialed in from the factory. The bolt carrier group uses 8620 black nitride steel, engineered for smooth cycling and easy cleaning. The included BAD Rack-15 C ambidextrous charging handle completes the package with smooth operation and no compromise on either shoulder.
This is a complete upper receiver assembly, so you're getting everything above the lower receiver. Pair it with any standard AR-15 lower and go to work—no smith required, no guesswork on headspace or bolt fit.
