Battle Arms Authority Elite Lower Receiver – Superb Lightweight Ambi AR-15 Billet Lower

Description

The Battle Arms Authority Elite Lower Receiver from Battle Arms Development is a premium billet AR-15 lower for builders who want the lightest, cleanest foundation for a custom rifle or pistol. It is CNC machined from 7075-T6 aerospace aluminum, uses BAD’s patent-pending lightweight design and weighs only 7.5 ounces. Sports South lists it as BAD model AE-LR-BLK under UPC 810033782183.

Battle Arms Authority Elite Lower Overview

Battle Arms Development is known for its lightweight AR parts and the BAD-ASS ambidextrous safety selector. The Authority Elite lower is the platform those parts were designed around. Material is strategically removed from non-critical areas to cut weight, while the areas that see stress keep full strength. The result is a billet lower receiver that looks sharp and helps keep an ultralight build under weight.

Ambidextrous Features

This ambidextrous lower is machined with relief cuts in the safety selector hole and internal wall for BAD’s short-throw reversible ambidextrous safety selectors, and it is properly marked for both 90-degree safeties and BAD’s short-throw selectors. Pictograph selector markings and multi-caliber markings give you flexibility for different builds. A flared, deep-beveled magazine well speeds reloads, and the trigger guard is integrated into the receiver.

Materials and Finish

7075-T6 aluminum is stronger than the 6061 used on many budget lowers, which matters on a lightweight design where material has been removed. BAD finishes the receiver with MIL-A-8625F Type III, Class 2 hard anodizing in black, inspects each one for dimensional accuracy and hand de-burrs sharp edges.

Planning Your Build

For an AR-15 build, you will need a lower parts kit, a buffer tube, buffer and spring, a stock or brace, and a complete upper. To get the full benefit of this receiver, pair it with BAD’s short-throw ambidextrous safety selector. The receiver ships stripped, and some BAD features, such as the set-screw bolt catch pin and captured detent spring, install differently from a standard lower, so read BAD’s instructions before assembly.

Why Builders Choose the Battle Arms Authority Elite Lower

Builders who chase every ounce on a lightweight carbine, competition rifle or AR pistol often start with the Battle Arms Authority Elite Lower because it is one of the lightest billet options available while still using standard parts. The ambidextrous-ready design suits left-handed shooters and anyone who trains to run the rifle from either shoulder. Its clean lines also make it a favorite for show-quality builds where appearance matters as much as performance.

Before You Buy the Battle Arms Authority Elite Lower

A stripped lower is the serialized part of an AR-15 and is legally a firearm, so it must ship to an FFL and follow the same transfer rules as a complete gun. Some states restrict AR-15 builds or features; confirm local law first. Premium billet lowers cost more than forged ones, and the value is in weight savings, fit and appearance.
