At 0.7 lbs, this stripped upper receiver adds minimal weight to your platform while maintaining the rigidity required for reliable bolt cycling, charging handle operation, and optic mounting surfaces. The compact 7.5-inch profile—measured along the receiver length—integrates seamlessly with standard AR-15 handguards and accessory rails, allowing you to optimize barrel length and sight radius based on your mission profile.

This component is ideal for experienced builders, gunsmiths, and tactical professionals who understand the critical importance of upper-receiver selection in overall system performance.

The stripped configuration allows you to pair this receiver with your choice of barrel profile, bolt carrier group, and charging handle, enabling complete customization. Compatibility spans all standard AR-15 furniture and optic mounts, making it a versatile foundation for everything from patrol carbines to precision rifles for sale or personal inventory.
