This is the genuine Heckler & Koch forearm rail (part number 702390), the same piece HK ships from the factory for the SL8, USC, and G36 family. It gives you roughly 4.5 inches of true Picatinny real estate to hang lights, lasers, small optics, or a grip, and it bolts right to the hard mounting points on your forearm. No cutting, no drilling, no permanent changes to the rifle.
The rail is machined from hardcoat anodized aluminum, so it stays light without giving up strength. The black anodized finish matches the factory look of an HK forearm and holds up to handling and weather, which matters when you're actually running the rifle and not just parking it in the safe. It's a clean, OEM-style match rather than a bulky aftermarket clamp-on.
What makes this piece handy is its flexibility. It can serve as either a side rail or a bottom rail depending on how you want the gun set up, and it uses the existing hard points on the forearm. The two included screws are all the hardware you need to get it seated. If you're building out an SL8 or USC and want to keep things factory-correct, this is the rail HK intended for the job.
One thing worth doing before you order: the SL8 line came in a few variations over the years, and the forearm mounting points can differ between them. Take a quick measurement of the hole spacing on your rifle so you know the rail lines up cleanly. Once it's on, you've got a stable, repeatable platform for whatever accessories you want to run, and you can always add a second one to the opposite side if you need more mounting space.
This factory rail is made for the HK SL8, USC, and G36 forearm. It mounts to the existing hard points on the handguard, so no modification to the rifle is needed. Because SL8 variants can differ slightly, measure your forearm hole spacing before ordering to confirm a clean fit.
Both. The 702390 is a universal forearm rail that works as either a side-mounted or bottom-mounted Picatinny section depending on how you want your setup configured. If you want rails on more than one surface, you can run additional pieces on the other mounting points.
Yes, this is a factory-original Heckler & Koch component, part number 702390, not an aftermarket copy. That means it carries the OEM fit and the black anodized finish that matches your HK forearm for a clean, built-in look.
It does. The rail ships with the two mounting screws needed to bolt it to the forearm. Installation is straightforward, though HK recommends any parts work be done by a qualified gunsmith if you're not comfortable doing it yourself.
