The 4.5" MPX carbon fiber handguard is made from Aerospace quality carbon fiber. The handguard employs the MPX retention pin for mounting the lower portion of the handguard to the front take down pin. A left and right CNC machined 7075 hardcoated aluminum rail attaches to the carbon fiber tube with fasteners to give a solid mount feel when the handguard is attached to the upper receiver.
The hanguard has M-Lok every 45 Degrees for a positive grip and for your finger and barrier stops. The tube size is 2.000"OD x 1.840"ID. Also the round tube has a more natural feel than the production and competitors part.
