Spike's Stripped Lower (crusader)

The Spike's Stripped Lower Receiver with Crusader markings is the foundation component for custom AR-15 rifle builds, designed for shooters and gunsmiths who demand precision engineering from the ground up. This stripped lower serves as the legally registered firearm component that accepts all standard AR-pattern upper assemblies, trigger groups, and stock configurations. Whether you're building a service rifle for competition, a duty platform for law enforcement, or a precision rifle for long-range work, starting with a quality stripped lower receiver is non-negotiable—it sets the accuracy and reliability ceiling for your entire build.

Spike's Tactical has established itself as a respected manufacturer through tight tolerances and consistent forging quality, and this stripped lower reflects that commitment. The receiver is precisely machined from 7075-T6 aluminum forgings to exact mil-spec dimensions, ensuring proper fitment with standard AR components and allowing for smooth trigger installation and upper receiver cycling. The Crusader marking provides visual identification while the stripped configuration—without fire control group, trigger, or stock—gives you complete control over component selection and customization to match your intended use, whether that's military-spec reliability or precision competition tuning.

This receiver is ideal for experienced builders, gunsmiths, and shooters who understand AR-15 assembly requirements and want to source each component individually for maximum control over trigger pull weight, stock ergonomics, and overall handling characteristics. As the regulated component in an AR-15 build, the lower receiver must be purchased through a licensed firearms dealer (FFL) and is subject to local and federal firearms regulations. Compatibility with standard AR-15 upper receivers, trigger groups, and buffer tube assemblies makes this a versatile foundation for carbines, rifles, and specialized platforms across all caliber options.
