Breek Arms Sentinel Caged Flash Hider for Breek-Lok 3QD | .30 Cal | 5/8×24 TPI
The Sentinel Caged Flash Hider by Breek Arms is a high-performance muzzle device designed to reduce muzzle flash and improve shooting control. This model is built for .30 caliber firearms and features a 5/8×24 TPI thread pitch, making it compatible with rifles chambered in .308 Winchester, 7.62x51mm NATO, and similar calibers.
Key Features:
Caged Design: The enclosed prong structure effectively disperses and redirects gases, minimizing muzzle flash while preserving the shooter’s night vision. The closed-end design also prevents the ringing sound common in open-prong flash hiders and reduces the risk of snagging on gear or environmental obstacles.
Breek-LOK 3QD Compatibility: This flash hider is fully compatible with the Breek Arms Breek-LOK 3QD system, enabling quick and secure attachment of compatible suppressors and accessories.
Durable Construction: Made from 4140 hardened steel with a nitride finish, the Sentinel Flash Hider is engineered for durability, corrosion resistance, and long-lasting performance.
Dimensions and Weight: Measuring approximately 2.25 inches in length and weighing about 1.8 ounces, this low-profile flash hider provides excellent performance without significantly altering the balance of the firearm.
Installation Considerations:
Thread Compatibility: Ensure your barrel is threaded in 5/8×24 TPI to guarantee proper fitment.
Proper Installation: A peel washer is included for correct timing and alignment during installation. Following manufacturer guidelines is recommended for optimal performance.
Barrel Length Recommendations: This flash hider is rated for use on barrels 14.5 inches or longer when paired with .308 caliber firearms.
Legal Compliance: Before installation, confirm that this flash hider complies with all applicable local, state, and federal regulations.
