The Geissele Super Modular Rails offer an ergonomic, modular and rigid handguard to suit a variety needs and missions. Each rail completely free floats the barrel and is machined from billet, aircraft grade aluminum. Rails interface with the receiver via a large barrel nut, to maximum surface area contact with the receiver. SMRs can be easily slid off the barrel nut, for cleaning and gas system maintenance. Each SMR includes a barrel nut and wrench for installation. MK2 features flat surfaces on sides and bottom. This SMR features a steel alloy barrel nut, for improved rigidity & strength. The MK2 also has a QD mount at the rear. Includes accessory rails.
