Shield Sa-15 Stripped Lower Fld Blk

The Shield SA-15 Stripped Lower Fld Blk is the foundation component every AR-15 builder needs to start a reliable, precision rifle platform. This stripped lower receiver is designed for shooters and gunsmiths who demand quality control over every stage of assembly—whether building a duty rifle, precision platform, or complete custom system. As a registered firearm component, the lower receiver is the serialized part that defines your build's legal identity and serves as the anchor for trigger group installation, magazine well geometry, and buffer tube mounting.

Shield Arms manufactures this stripped lower in field-grade finish, balancing durability with cost-effectiveness for professional and civilian builders alike. The flat-top design accepts standard AR-15 upper receivers without modification, and the magazine well is cut to mil-spec dimensions for universal compatibility with all standard AR-15 magazines. Weighing 1.38 lbs and dimensioned at 6.5 × 2.5 × 9.75 inches, the compact profile integrates seamlessly into any build configuration—carbine, mid-length, or rifle-length systems—while the hardcoat anodized finish resists corrosion and wear in field conditions and storage. The receiver itself comes unfired and unassembled, allowing complete customization of your trigger, selector, and safety components.

This stripped lower is ideal for law enforcement armorers, military personnel, competitive shooters, and civilian builders who require parts-level control and accountability. Installation pairs directly with any standard AR-15 upper assembly and functions with mil-spec buffer tubes, pistol grips, and trigger groups. Whether you're building your first rifle or assembling a fleet of duty weapons, the Shield SA-15 stripped lower provides the regulated foundation necessary for a battle-tested platform that performs reliably in training, competition, and operational environments.
