Please note that installation of a free float quad rail requires additional tooling and gunsmithing expertise. We recommend consultation with an experienced gunsmith. When installing the barrel nut, we recommend using 30-35 lbs of torque. The barrel nuts are made from 6061 grade aluminum which, although significantly lighter than steel barrel nuts, can be damaged under excessive force. All Monstrum Tactical rail and accessory products are backed by a lifetime replacement guarantee. Monstrum Tactical only sells through and provides support for purchases made through our Monstrum Tactical store.
