Spike's Stripped Lower (spider)

The Spike's Stripped Lower (Spider) is a precision-machined AR-15 lower receiver designed for shooters who demand reliability in both duty and recreational applications. As a stripped lower receiver, this component serves as the regulated firearm foundation onto which you'll assemble the upper receiver, bolt carrier group, and trigger assembly to create a complete rifle platform.

Machined from 7075-T6 aluminum forgings, this lower receiver features a durable anodized coating that resists corrosion and wear during field operations. The spider design reference denotes the distinctive, reinforced internal geometry that provides structural integrity at critical stress points where the trigger group and magazine well intersect. This design ensures that the receiver maintains its strength while remaining lightweight.

Compatible with standard AR-15 upper assemblies and parts kits, the Spike's Stripped Lower allows builders and gunsmiths maximum flexibility in configuring rifles for specific missions or preferences. Whether you're assembling a patrol rifle, precision platform, or specialized tactical configuration, this receiver is trusted by law enforcement armorers and military personnel for its consistent quality and attention to detail.
