The Angstadt Arms 13.5" free-float hand guard is the ideal choice for your next rifle build. Its unique design features a skeletonized top rail which provides added weight savings by removing sections of the Picatinny rail and replacing them with an M-LOK mounting interface. The handguard also has two QD swivel mounting points and is compatible with both forged and billet upper receivers chambered for 223/5.56 and 9mm. Includes hardware.
