This lower build kit gives you a fully functional lower receiver assembly ready to pair with any AR-15 upper. You get a serialized Davidson Defense lower receiver in 7075-T6 forged aluminum, a complete mil-spec lower parts kit, and an Adaptive Tactical EX adjustable stock that handles everything from precision shooting to dynamic movement. The Type III hard coat anodized finish protects against wear, and the 6-position buffer tube lets you dial in length of pull for your specific setup.
The Davidson Defense lower receiver is forged from 7075-T6 aluminum, the same material used in aerospace and precision applications. The Type III hard coat anodize provides corrosion resistance and durability through extended use. This is the serialized component that legally defines the firearm, and it arrives ready to accept your choice of upper assembly. The trigger well is engraved but unmarked by branding, keeping the platform clean and neutral.
The Adaptive Tactical EX stock is a six-position adjustable system that lets you match length of pull to your shooting style, body armor, or gear configuration. Unlike fixed stocks, the EX gives you flexibility without adding bulk. The stock mounts to the mil-spec heavy-duty buffer tube and includes a QD sling mount for rapid attachment and detachment. The sling loop provides a secondary mounting point if you prefer traditional sling setups.
The kit includes a standard carbine recoil buffer at 3 ounces, matched to a mil-spec carbine recoil spring. This combination cycles smoothly with most mid-length and carbine-length uppers. The mil-spec heavy-duty buffer tube handles the spring and buffer while the M16 receiver end plate and carbine castle nut secure everything in place. All components are standard mil-spec dimensions and fully compatible with aftermarket uppers.
Every internal component needed to complete the lower receiver is included. Trigger group, hammer, disconnector, selector, magazine catch, bolt catch, and all associated pins and springs come pre-assembled or ready for final installation. The mil-spec A2 grip is standard and comfortable, though you can swap it for any AR-15 compatible grip if you prefer different ergonomics later.
Lower receiver not included in upper assemblies. Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws.
