Battle Arms BATTLEARMS Ambidexterious Lower 7075-T6 Billet Receiver Set - Black Anodized Finish - BAD556-SET

The BAD556 Ambidextrous Lightweight Billet Lower Receiver delivers premium materials and practical features for high‑performance AR builds. CNC milled from 7075‑T6 aerospace aluminum, the BAD556 combines strength with a patent‑pending lightweight profile that shaves weight while preserving structural integrity. Finished in MIL‑A‑8625F Type III Class 2 hard anodize, this lower is built to withstand heavy use and harsh environments.

Designed for modern shooters and builders, the receiver includes ambidextrous bolt release and magazine release provisions and is machined to accept Battle Arms Development short‑throw/reversible safeties (relief cut on selector hole/internal wall). The flared, deep‑beveled magwell speeds reloads, and the integrated trigger guard improves ergonomics and durability. Builders will appreciate the dimensional accuracy inspection, hand‑deburred edges, included set screws, captured detent spring, and tension screw for easy assembly and reliable function. Laser‑engraved logos and multi‑caliber markings finish the package. Everything—components, material, and packaging—is made in the USA. Build a light, reliable, ambidextrous platform with the BAD556 — available now at AR-15 Discounts.
