What Is the AR-15 Lite Lower Parts Kit?

An AR-15 Lite LPK is a specialized lower parts kit that provides the core pins, springs, detents, and controls for completing a stripped lower receiver while leaving out heavier or redundant components. This makes it ideal for weight-conscious builders who want a rifle that’s fast-handling, easy to carry, and still built on dependable mil-spec dimensions.

Key Features

• Lightweight Design – Reduced overall weight for a lighter rifle build.

• Essential Components Only – Provides the small parts needed to finish your lower without extras you don’t need.

• Durable Build – Manufactured from high-quality materials for long service life.

• Mil-Spec Compatibility – Fits AR-15 lowers built to standard dimensions.

• Builder-Friendly – Streamlined for competitive shooters, hunters, and tactical users who prioritize speed and handling.

What’s Included

The KAK AR-15 Lite Lower Parts Kit comes with:

• Safety selector, spring, and detent

• Takedown and pivot pins with detents and springs

• Magazine catch, button, and spring

• Bolt catch, plunger, and spring

• Buffer retainer and spring

• Trigger guard (billet version included)

• Small pins and roll pins for assembly
