The Ballistic Advantage AR-15 lower receiver (brand part no. BAPA100039) is machined from 7075-T6 forged aluminum with a hard-coat anodized finish, built as a mil-spec-quality foundation for a custom build. It features a nylon-tipped upper tension screw for a tight fit with any standard AR-15 upper, a flared magwell for easier magazine insertion, and a rear takedown pin detent hole threaded for a 4-40 set screw. Selling it stripped keeps cost down while these small design details add up to a receiver that fits and functions better than a bare-bones forging. It’s a strong choice for builders who want thoughtful touches without paying for a billet receiver.
