Installation Instructions and Video

See the video for instructions. You'll need at least a wrench for installation – preferably a torque wrench with suitable sockets. The sockets appear to be inch-sized 5/8" and 13/16" – so metric sockets 16mm and 21mm might also work. In the video, the person talks about "inch-pounds," but the actual torque values are in "foot-pounds" (ft-lbs), as indicated on the stock attachment parts. Tighten the buffer tube to 35 ft-lbs / about 47 Nm of torque, and the rear screw to 25 ft-lbs / about 34 Nm.
