Wanted to try this out while I’m waiting for my Form 1 to clear on my converted USC. It was easy to install, fit perfectly, and looks great. The shroud is plastic, but the picatinny rails are metal.
The Extended Handguard for the HK USC covers up that excess barrel length while adding over 3' of rail space for added mounting options. The design also now includes a built-in steel QD sling socket.
The assembly is made up of a nylon core attached to the USC via 3 12" aluminum rails. The rails mount to the USC using the 6 factory rail mounting points with included hardware. No modifications to the firearm are required.
This core is manufactured from Nylon using a process called Multi Jet Fusion or MJF. The parts are then sandblasted, dyed and shotpeened for a strength and finish that is comparable to injection molded nylon. The part is black throughout.
There is no room beneath the handguard to mount any type of barrel shroud or suppressor.
