The KAK Industry KF-15 (brand part no. MO-801-0604-001) is a forged AR-15 stripped lower receiver, the foundational framework for building a custom AR-15 or AR-10-pattern rifle. KAK Industry offers a broad lineup of lower receivers for shooters who want the versatility and customization AR-15s are known for, letting builders match parts and accessories to their own shooting style and ergonomic preferences. Selling it stripped keeps costs down and puts trigger, safety, and buffer selection in the builder’s hands. It’s a solid, no-frills starting point whether building from the ground up or upgrading an existing platform.
