Aero Precision M4E1 Stripped Lower Receiver Special Edition: Thunder Ranch Anodized APAR600016C

This M4E1 Lower Receiver delivers billet aesthetics in a forged package. It includes an obvious skeletonized magwell along with a specialized Thunder Ranch serial number range along with the Thunder Ranch logo. This custom designed enhanced forging is machined from 7075-T6 Aluminum and compatible with all mil-spec AR15 parts. Aside from the visual upgrades this custom engineered design provides, it also challenges the much more expensive billet options. We’ve also added several functional features to the lower receiver to simplify the assembly process for the at home builder.
