BRT Closed-Type Reactive Muzzle Brake for PKM

The **BRT Bars Gas-Relief Muzzle Brake** for PKM in caliber .30/7.62mm is an exceptional tool for equipping firearms designed for intensive firing. Unlike standard closed gas-circuit muzzle devices, the Bars series features a straight-flow system that prevents internal gas bubbles, reducing pressure and stress on components.

Advantages of the gas-relief system:

• Significant reduction of internal gas bubbles;
• Lower internal pressure;
• Minimal impact on weapon ballistics;
• Fully compatible with automatic fire modes.

Benefits of the closed-type muzzle brake:

• Reduces recoil and muzzle rise;
• Decreases sound pressure and redirects it away from the shooter;
• Eliminates flash for effective nighttime use, including with night vision devices;
• Reduces smoke at the muzzle.

The Bars series is specifically engineered for military units requiring durable muzzle brakes capable of enduring high-round counts. The device has no coating, as testing revealed coatings fail under prolonged intense firing.

Our Testing Rating

The Bars muzzle brake, like all gas-relief systems, reduces sound less but excels in sustained burst firing compared to lightweight closed-circuit alternatives.

Alignment Check Before Firing

Proper alignment is crucial when installing a closed-type muzzle brake to prevent bullet collisions with chamber walls. Typically, weapon threading is precise, ensuring immediate functionality. However, issues often arise with 24x1.5R threading on AK-74/AK-74M/Saiga-MK models due to misaligned front sight bases. If uneven, the base edge can be filed down (manually or professionally) for even contact with the brake.

Refer to the diagram below for correct installation. View from the front, aligning the breech with a light source or white paper for clarity.
