The KAK Industry AR-15 LPK (Lower Parts Kit) without grip and trigger guard is purpose-built for builders who want full control over their lower receiver assembly. This stripped kit gives you all the essential components to complete a functional lower—fire control group, bolt catch, magazine release, springs, detents, and pins—minus the grip and trigger guard, so you can choose aftermarket ergonomics that match your shooting style and mission. It's a smart move if you already have a favorite grip or guard in your parts bin, or if you're building multiple uppers around a single lower and want consistency across your platform.
Every part in this kit is manufactured to mil-spec dimensions and 100% American made, meaning you get the same durability and compatibility you'd expect from a complete factory lower—just more flexibility in the final assembly. Whether you're a competition shooter, hunter, or recreational marksman, building from a quality parts kit keeps your labor costs down and lets you spec the gun exactly how you want it.
Assembly is straightforward for anyone with basic gunsmithing knowledge and the right pin punch set. The kit includes everything needed to function; pair it with a buffer assembly, your choice of upper receiver, and you're ready to shoot. No guesswork, no missing detents rolling across the workbench at 2 a.m.

This kit includes the complete fire control group (hammer, trigger, disconnector, and associated springs), bolt catch, magazine release, and all springs, detents, and pins needed to assemble your lower receiver. It does not include a pistol grip or trigger guard, allowing you to add those separately.
Yes. All parts are made to mil-spec dimensions, so they'll function in any mil-spec AR-15 lower receiver. You'll need to source a compatible pistol grip and trigger guard separately.
With this lower parts kit, you'll also need a lower receiver, upper receiver assembly, buffer assembly kit, and your choice of pistol grip and trigger guard. This kit supplies only the internal lower parts.
Assembly requires basic gunsmithing knowledge and the proper tools (pin punches, typically). If you're new to AR building, consider a detailed assembly guide or instructional video. Many experienced builders complete assembly in under an hour.
