An LBE Unlimited AR-15 lower parts kit gives you the internal components you need to assemble a complete lower receiver without starting from scratch. This kit includes the springs, pins, and hardware that make up the fire control group and related mechanisms—everything except the pistol grip and trigger guard, so you can choose those parts to suit your build's ergonomics and legal requirements. Whether you're building a custom rifle from an 80% lower, replacing worn internals, or assembling a specialized configuration, this kit eliminates the hassle of sourcing individual parts.
LBE Unlimited has built a reputation for no-frills, reliable AR components. This lower parts kit is stripped down to essentials, letting you control the final look and function of your rifle. The absence of a pistol grip and trigger guard means you have full freedom to select parts that match your intended use—whether that's a featureless setup for restricted states, a competition-grade ergonomic grip, or a tactical configuration.
The kit comes in black and includes all the small parts—detent springs, selector detents, hammer and trigger pins, safety selector, and the hardware necessary for proper lower assembly. Quality control and fit are consistent across LBE components, so you can focus on the build rather than troubleshooting fitment issues. This is exactly the kind of no-nonsense product that appeals to builders who know what they're doing and want to avoid the markup on pre-assembled kits.
| Brand | LBE Unlimited |
| Model | AR15LPK |
| Finish | Black |
| Includes | Lower parts kit (pins, springs, screws, and hardware); excludes pistol grip and trigger guard |
The kit includes all the springs, pins, selector detents, hammer and trigger pins, safety selector, and associated hardware needed to assemble a complete lower receiver. Pistol grip and trigger guard are not included, allowing you to select those parts separately.
Excluding these parts gives you the flexibility to choose components that match your build's purpose and comply with your local regulations. Some states require featureless grips, others allow standard mil-spec, and competition or specialty builds may call for premium aftermarket options.
Beyond this kit, you'll need a lower receiver (either 80% and completed, or already finished), a pistol grip, a trigger guard, and the upper assembly to finish a complete rifle. This kit supplies the internal fire control components only.
Yes—this kit is designed for standard AR-15 lower receivers and includes components that meet mil-spec dimensions and fitment.
