BCM KMR 13" Handguard (and Upper Receiver, BFH)

The BCM KMR 13" handguard is a modular upper receiver component recognized for its lightweight construction and advanced materials.

• It utilizes the KeyMod rail system, allowing for highly modular accessories while maintaining compatibility with standard Picatinny rails.
• The handguard is constructed from a blended aluminum and magnesium alloy, making it 30-40% lighter than standard aluminum.
• It features a proprietary, plasma-deposited ceramic coating developed for the aerospace industry, offering superior wear and corrosion resistance.
• Design includes an indexing and lock-up system to mitigate rail movement when exposed to heat generated by the barrel nut.
