BRC-1O The SENTINEL in 243 WIN
The Sentinel is an uncompromising blend of precision, performance, and craftsmanship. Chambered in .243 Winchester, it’s purpose-built for those who demand flat trajectories, minimal recoil, and long-range capability in a refined, lightweight platform.
Renowned for its speed and accuracy, .243 WIN offers exceptional ballistic performance—ideal for precision shooters, predator hunters, and those who require reach and reliability in the field. Paired with a Proof Research carbon fiber barrel, the Sentinel delivers repeatable accuracy, reduced weight, and outstanding heat dissipation for consistent performance over extended sessions.
Meticulously machined from billet 7075 T6 aluminum, the Sentinel is assembled by skilled artisans in Fort Worth, Texas, with a relentless focus on fit, finish, and function. Designed for balance and control, it performs with quiet authority—on the bench, in the blind, or across open ground.
Each rifle ships with a PMAG® 20 LR/SR GEN M3™ magazine and is backed by a Limited Lifetime Warranty. Proudly designed, machined, and assembled in the USA.
The Sentinel isn’t simply built. It’s the benchmark for the modern precision rifle.
