Yes it's a light, small, simple wrench only designed for your buttstock/buffer tube castle nut. If you want a lightweight tool for that nut, this will hardly be noticed in your equipment bag. This is ideal for you guys that are installing AR stock conversion kits for other types of firearms.

Note this hook style is designed for the older style nuts that had a simple hole in the side of the nut. You can also use this on castle nuts with the notch but need to take more care to ensure the wrench does not slip off.

  • For tightening/loosening the castle nut on the buffer tube only
  • Looks like stamped painted aluminum
  • Also works well as a hook to pull people along by their noses 
  • Weight: 42g

  • (1) Castle Nut Wrench
