Battle Arms Development Authority Elite Complete Upper Features The Battle Arms Development Authority Elite upper is machined from a billet BAD556 7075-T6 aircraft-grade aluminum receiver giving the upper a stronger more precisely fitted foundation than a standard forged part. Integral ambidextrous controls are built into the receiver itself so left and right-handed shooters get the same ease of manipulation without aftermarket parts. The 16 inch barrel is cut from 4150 chrome-moly steel and finished in black nitride a combination that resists corrosion and wear while standing up to sustained use. The barrel is individually head-spaced and paired with a matching 9310 steel bolt and 8620 black nitride carrier which together improve reliability and make the bolt carrier group easier to clean after a hard range day. A free-float M-LOK handguard wraps the barrel with attachment points at the 3 6 and 9 o clock positions letting the shooter mount lights grips or bipods exactly where they are needed. At the 12 o clock position sits a full-length Picatinny rail with Battle Arms Development s signature notch cut matching the upper giving a continuous flat mounting surface for optics. The included Bad Rack-15 C ambidextrous charging handle allows fast snag-free manipulation from either side of the rifle a real advantage for shooters working from cover or off-hand positions. Finished in a durable black anodized coating and shipped complete with its own bolt carrier group the Authority Elite upper is a drop-in duty-ready solution for sale at GrabAGun.
