HK 702390 Picatinny Rail Black Aluminum SL8/USC

The HK 702390 is a factory Picatinny forearm rail section from Heckler & Koch (HK), engineered for the SL8 and USC rifles. Machined from quality aluminum and finished in a low-glare black hardcoat anodized coating, this rail gives SL8 and USC owners a rugged, factory-spec mounting platform for lights, lasers, and other accessories on the forend of these H&K platforms.

The rail supplies approximately 4.5" of usable MIL-STD-1913 Picatinny rail and installs onto the side of the forearm using the included mounting hardware. Its low-profile design integrates cleanly with the host firearm and provides a standardized 1913 Picatinny interface for clamping on weapon lights, red-dot mounts, or foregrip accessories without modification to the factory handguard.

Sold in new factory condition and packaged as a complete rail section with installation screws, the 702390 is the correct factory rail for anyone looking to expand the accessory-mounting capability of an HK SL8 or HK USC.
