Description

The Battle Arms Development BAD556-LR Lower Receiver in 223 Rem/5.56 NATO is a precision-machined component engineered for shooters and gunsmiths building or upgrading AR-15 platforms. As a fully functional lower receiver, this component serves as the serialized foundation of any modern sporting rifle or duty carbine, making it essential for those seeking a quality base platform. Whether you're assembling a precision rifle, tactical patrol carbine, or sport shooting build, this Battle Arms Development lower receiver provides the structural integrity and dimensional accuracy required for reliable function and longevity.

Manufactured from 7075-T6 aluminum and finished in mil-spec black anodize, the BAD556-LR delivers corrosion resistance and durability suitable for field and training environments. The black anodized finish protects against oxidation while maintaining a professional, low-visibility appearance. Weighing 0.88 pounds, this lower receiver is lightweight without compromising material strength, and its compact dimensioning (6.7 x 3 x 10 inches) fits standard AR-15 upper assemblies and fire control groups. Battle Arms Development's manufacturing standards ensure tight tolerances throughout the receiver, critical for bolt carrier group fit, trigger function, and long-term reliability under sustained use.

This lower receiver is ideal for law enforcement armorer builds, military small arms programs, and civilian shooters requiring a dependable platform. Compatibility spans standard AR-15 trigger groups, buffer tubes, and upper receivers chambered in .223 Remington or 5.56 NATO. Installation requires familiarity with AR-15 assembly; proper headspace verification and fire control group installation are mandatory before function testing. As the regulated component of an AR-15 system, this lower receiver comes with all legal requirements met and is ready for integration into your complete rifle build or refurbishment project.
