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 complete upper includes our popular ATLAS R-ONE Handguard! The R-ONE handguards are designed with size and weight in mind, while still providing plenty of real estate to accommodate any attachment needs the end user may have. Our proprietary ATLAS attachment system is a durable and dependable mounting platform, maintaining a slim profile while still providing the strength and stability customers have grown to love from Aero Precision handguards.
