Spike's Stripped Upper/lower Set Fde

The Spike's Stripped Upper/Lower Set FDE provides the foundational platform for custom AR-15 builds, delivering the precision starting point that law enforcement armorers and military gunsmiths require. This stripped receiver set eliminates proprietary restrictions, giving builders complete control over component selection and configuration. Whether you're assembling a duty rifle, precision trainer, or specialized platform, the modular nature of this set accommodates virtually any mission requirement without factory limitations.

Spike's Tactical machines these receivers from forged aluminum to mil-spec dimensions, ensuring dimensional consistency critical for reliability under sustained operations. The Flat Dark Earth finish offers superior corrosion resistance in varied environments while maintaining a low-visibility profile suitable for tactical deployment. At 1.06 lbs for the complete set, the weight permits optimal balance when integrated with furniture and optics, a factor that directly impacts shooter fatigue during extended patrol or training cycles. The stripped configuration—devoid of fire control groups, stock hardware, or upper assembly components—allows operators to specify trigger breaks, buffer systems, and grip ergonomics tailored to individual or unit standards.

Field-proven by active-duty personnel and law enforcement agencies, the Spike's Stripped Upper/Lower Set FDE excels for those building duty rifles, patrol carbines, or training systems from scratch. Installation compatibility spans standard mil-spec AR-15 components, making integration straightforward for experienced builders or professional gunsmiths. The compact footprint and precise machining ensure zero headspace issues and reliable cycling across diverse ammunition and caliber conversions, positioning this receiver set as the preferred choice for modular platform development.
