ACI ACI-15 stripped lower receiver for AR-15 platform builds. Precision-machined aluminum construction ready for your custom assembly.
The ACI ACI-15 stripped lower receiver provides the foundation for building a custom AR-15 platform rifle. As a stripped lower, this component arrives without internal parts, allowing you to select and install components that match your specific shooting needs and preferences.
A stripped lower receiver is the regulated component of an AR-15 rifle and requires proper registration and compliance with all applicable federal, state, and local laws. You'll need to source a trigger group, hammer, safety selector, and other internal components separately to complete your build. This approach gives you maximum flexibility in selecting parts that suit your intended use—whether for target shooting, hunting, or sport competition.
The ACI ACI-15 is an excellent choice for builders who want quality construction without paying for pre-installed components they may want to replace.
