Ballistic Ba10 308 Lower Receiver

The Ballistic Advantage BA10 308 Lower Receiver is a precision-manufactured foundation component for building a complete AR-platform rifle in .308 Winchester. Built to mil-spec dimensions, this lower receiver enables operators, precision shooters, and firearms builders to construct a large-format AR from the ground up with components that interface correctly and function reliably under demanding conditions.

Mil-spec geometry ensures compatibility with standard AR-308 parts, magazine wells, fire control groups, and buffer systems. The receiver's coating provides corrosion resistance and durability in field environments, critical for platforms subjected to extended training cycles, deployment conditions, or harsh storage. At 0.81 lbs, the lower receiver contributes minimal weight to the overall rifle while maintaining the structural integrity necessary for .308 Winchester's sustained recoil impulses and precision accuracy requirements. The BA10 lower is the starting point for custom builds where component selection, accuracy tuning, and ergonomic configuration are prioritized.

This receiver serves precision rifle competitors, long-range hunters, military and law enforcement trainers, and serious sport shooters building modular .308 platforms. The mil-spec standard ensures the receiver will accept parts from multiple manufacturers without fitting issues, providing flexibility in trigger selection, stock configuration, and fire control customization. Users building a BA10-based rifle gain a platform capable of supporting match-grade accuracy while maintaining the modularity that makes AR-platform rifles cost-effective to maintain and upgrade.
