What You Need to Know
As a stripped lower receiver, this component is the regulated part of an AR-platform rifle and requires proper licensing and compliance with all applicable federal, state, and local laws. You'll need to source a complete fire control group, buffer tube assembly, stock, and pistol grip to complete your build.
The multi-caliber design means you can swap upper receivers to change calibers without purchasing additional lower receivers, making this an economical choice for shooters who want flexibility in their platform.
