Building or rebuilding an AR-15 lower receiver? The LBE Unlimited AR-15 complete lower parts kit gives you everything you need in one package—no hunting down individual components or compatibility headaches. This is the foundation of a custom AR build: the kit includes the trigger group, selector, safety, and all the small parts and springs that make a lower function, plus the A2-style pistol grip and trigger guard. You get genuine LBE Unlimited parts in hard-anodized black, designed to work together out of the box. Whether you're assembling your first rifle, upgrading an existing lower, or stocking up for a project, a complete kit like this saves time and takes the guesswork out of parts selection.
Lower parts kits are the practical choice for builders who want quality, consistency, and simplicity. Instead of sourcing a safety here, a trigger guard there, and hoping everything fits, this kit delivers matched parts that work. LBE Unlimited has built a reputation for no-nonsense gear that works hard, and this lower parts kit is no exception. The A2 grip is a proven control surface—ergonomic enough for shooters of all experience levels—and the included trigger guard fits standard lower receivers as designed.
Installation is straightforward for anyone with basic gunsmithing experience or a quality build manual. These parts are ready to go into your stripped lower receiver; all you need is a quality takedown pin set (if not included in your kit) and standard gunsmithing tools. Perfect for hunters, precision shooters, sport competitors, or anyone building a rifle configured exactly the way they want it.
| Brand | LBE Unlimited |
| Product Type | AR-15 Lower Parts Kit |
| Included Components | Pistol grip, trigger guard, trigger group assembly, selectors, safeties, springs, and small parts |
| Grip Style | A2-Style Pistol Grip |
| Finish | Hard-Anodized Black |
| Compatibility | AR-15 Lower Receivers |
This complete lower parts kit includes the A2-style pistol grip, trigger guard, and all the internal parts you need to complete a lower receiver: the trigger group, selectors, safeties, springs, and associated small parts. You'll have everything except the stripped lower receiver itself and takedown pins (which are often sold separately).
Yes, this kit is designed for standard AR-15 lower receivers. The parts are manufactured to fit AR-15 specifications. Always verify your lower receiver is marked for .223/5.56 or your intended caliber before assembly.
Some familiarity with AR assembly is helpful, though many builders successfully install lower parts kits following a quality build guide and using basic gunsmithing tools. If you're new to AR builds, we recommend studying an assembly manual or watching a reputable video walk-through before starting.
The A2-style grip is a classic, time-proven control surface that works well for most shooters and shooting disciplines. It has a traditional angle and texture. Other grips offer different angles, textures, or ergonomic features—it comes down to personal preference and your shooting style.
