BCM KMR Alpha 5.56 13" Black

Features

The BCM KMR Alpha 5.56 13" Black is a lightweight and durable handguard designed for AR-15 rifles. It is constructed from high-quality aluminum and features a proprietary mounting system that ensures a secure fit and mitigates movement under heat generated from the barrel nut. The handguard includes a hardcoat anodized finish, providing corrosion resistance and a non-reflective surface.

Specifications

The handguard is 13 inches in length and has a 1.3-inch inner diameter. It features a flat-to-flat outside dimension of 1.5 inches and flares forward at the 3 and 9 o'clock positions by approximately 1/4 inch. The actual length of the handguard when measured to the flare is 15 inches. The handguard alone weighs 8.6 ounces, and the mounting hardware adds an additional 2.4 ounces, resulting in a total weight of 11 ounces.

The BCM KMR Alpha 5.56 13" Black is designed for rifle-length AR-15s and is compatible with mil-spec diameter barrels with a maximum diameter of 1 inch. The handguard allows for a larger range of modularity, offering four different offset mounting positions between traditional 3, 6, 9, and 12 o'clock positions. This feature enhances modularity and provides a more versatile accessory mounting system.

KeyMod Interface System

The KeyMod interface system was developed by Eric Kincel, now the Director of BCM's product development team. It works in parallel with the current Picatinny system and advances modularity beyond the standard 1913 rail system. The KeyMod system allows for universal modularity between various manufacturers of accessories and accessory rails, ensuring compatibility and ease of use.

Construction and Materials

The BCM KMR Alpha 5.56 13" Black is manufactured from high-quality aluminum, providing a lightweight yet durable construction. The handguard features a hardcoat anodized finish, which enhances corrosion resistance and provides a non-reflective surface. This finish also helps maintain a clean and professional appearance.

Modularity and Versatility

The handguard's KeyMod interface system allows for a larger range of modularity, offering four different offset mounting positions between traditional 3, 6, 9, and 12 o'clock positions. This feature enhances the versatility of the handguard, providing a more comprehensive accessory mounting system. The KeyMod system also allows for direct mounting of modular accessories, which helps in reducing bulk and weight, making the weapon system lighter and cleaner.

Sling Mount

The BCM KMR Alpha 5.56 13" Black includes a BCM KeyMod Sling Mount, providing additional versatility and ease of use. This feature allows for the attachment of slings or other accessories, enhancing the functionality of the handguard.

Safety and Usage

When securing KeyMod fasteners on polymer accessories, it is recommended not to exceed 20 inches per pound of torque. For aluminum Picatinny rail sections, the recommended torque is 30 inches per pound. This ensures safe and secure mounting of accessories, minimizing the risk of damage or malfunction.

Conclusion

The BCM KMR Alpha 5.56 13" Black is a premium handguard designed for AR-15 rifles. Its lightweight and durable construction, along with the proprietary mounting system, make it a versatile and reliable accessory.
