BCA-1O The SENTINEL in 8.6 Blackout
The Sentinel is an uncompromising blend of power, precision, and craftsmanship. Chambered in 8.6 Blackout, it’s purpose-built for those who prioritize suppressed performance without sacrificing accuracy, reliability, or presence.
Designed around heavy, high-mass projectiles, 8.6 Blackout delivers devastating terminal ballistics at close to mid-range, whether in subsonic or supersonic form. It excels with shorter barrels and suppressors, making it a formidable choice for hunters, tactical applications, and professionals who value both stealth and stopping power.
Meticulously machined from billet 7075 T6 aluminum and fitted with a Proof Research carbon fiber barrel, the Sentinel balances strength and lightweight control with refined recoil management and repeatable precision.
Built by skilled artisans in Fort Worth, Texas, it reflects a relentless commitment to quality. Designed for exceptional handling and confidence in every shot, the Sentinel elevates the standard for modern suppressed rifles.
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 suppressed rifle.
