The Blackhawk AR15 Quad Rail replaces handguards with no modifications to the weapon. Its interlocking halves are secured using six screws for extra strength and stability. The slim profile is for a more comfortable, handguard-like feel, and limited rotation push-button sling swivel attachment points that are incorporated on left and right sides. It also has an unique vent hole design helps dissipate heat and reduce weight.
