Installation Instructions Handguard Installation instructions In order to install your new handguard you will need the following tools: 30mm Wrench 5/32" Hex Screwdriver Thread Locker (optional) Once you have installed your barrel in your upper receiver thread the barrel nut onto the upper and tighten down to 35-40 foot pounds. After you have installed your gas block and tube assembly slide the handguard over the barrel nut. You may apply Loctite to the exterior of the barrel nut across the knurled surface for added grip. You will need to apply some force to the rail when going over the barrel nut as the knurling is designed to mar the interior surface of the rail adding additional grip. Align the rail with your receiver and put the mounting screws in the drilled holes from the left side of the upper receiver and proceed to tighten them down to 3 foot-pounds (36 inch-pounds). Do not torque screws more than 3 foot-pounds. Exceeding this force may strip the threads.
