Frequently Asked Questions
Lower Receivers
What are good lower receivers?
Aero Precision M4E1 and Palmetto State Armory are widely recommended for AR-15 builds. Cross Machine Tool and BCM also earn strong marks. Prices typically range $99–$431 depending on features and finish.
Are 80% lower receivers illegal?
Federal law doesn't classify 80% lowers as firearms, so they generally don't require serial numbers or background checks. However, the ATF's 2022 rule was not fully struck down — the Supreme Court's VanDerStok v. Garland decision addressed ATF authority but left parts of the rule intact. Check your local laws before purchasing.
What is the purpose of a lower receiver?
A lower receiver houses the trigger assembly, hammer, and sear—the fire control group that makes a rifle function. It's the serialized part legally classified as the firearm itself. The lower also anchors the stock and buffer tube, serving as the structural backbone for AR-platform builds.
Why are lower receivers out of stock?
Stock levels fluctuate with demand and production capacity. Even common budget brands like Anderson and Aero Precision face shortages, with many distributors running low. Check multiple retailers frequently for current inventory.
