Aero Precision Combines with the Famous Thunder Ranch to Deliver This Unique Lower Receiver

The Thunder Ranch product line is a joint venture between Aero Precision and Thunder Ranch. Aimed to achieve Clint Smith's ideal purpose built "Ultimate Carbine", these products include key features requested from Clint Smith himself but with an Aero Precision flare. Like everything surrounding the Thunder Ranch name, you get exactly what you need - nothing more and nothing less.

This M4E1 Lower Receiver delivers billet aesthetics in a forged package. It includes a skeletonized magazine well, 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 AR-15 parts. Aside from the visual upgrades this custom engineered design provides, it also challenges the much more expensive billet options. Aero has also added several functional features to the lower receiver such as a threaded bolt catch pin and threaded takedown pin detent recess in order to simplify the assembly process for the at home builder.
