KAK Industry KF-15 Complete Lower Receiver - Black

The KAK Industry KF‑15 Complete Lower Receiver is the ideal foundation for any AR‑15 build—whether you're assembling your first rifle or upgrading an existing platform. Machined from USA‑produced 7075‑T6 forged aluminum, this lower delivers exceptional strength, durability, and long‑term reliability. Finished in a deep matte Type III Class II hard‑coat anodize, the KF‑15 offers superior corrosion resistance and a clean, professional appearance.

Designed to accept all mil‑spec lower receiver components, the KF‑15 includes a mil‑spec buffer tube and buffer, KAK lower parts, and an A2 grip—giving you a complete, ready‑to‑pair lower that meets strict quality standards. The M4‑style fire control group pocket, pictogram selector markings, and upper‑receiver tensioning screw threads ensure compatibility, smooth operation, and a tight, rattle‑free fit with your upper.
