The new Switch MOD 2 Series takes the very best from the Switch Series and fine tunes it. The full length 12 o’clock picatinny rail has been eliminated in favor of open vents for heat dissipation and shorter lengths of rail at the front and rear for optics or back up iron sights. This gives a more streamlined appearance to the rail” but more importantly” allows the shooter to utilize the smaller diameter of the rail to manipulate the rifle more effectively. The vents allow better airflow from the barrel and helps eliminate heat buildup and allows the end user to run longer and cooler with this setup. Additional 45 degree M-LOK sections have been added up front to give the flexibility and freedom to run offset lighting solutions. The Switch is extremely lightweight and features a patent pending locking mechanism that allows tool-less removal of the rail. A spanner wrench is needed to torque the barrel nut to spec (not included).
