PRODUCT FEATURES
The signature Black Diamond® Handguard on this carbine Top End bridges the gap between the upper receiver and handguard and is marked for position on all 4 sides. The now famous Black Diamond® pattern reduces weight while providing air vents to cool the barrel. It also blends perfectly with our diamond fluted barrels.
