Review on Versatile Spanner Nut Wrench Tool: Ideal for Floor Heating Pipes and Cars Walnut, Features Non-Slip Handle by Chris Horton

Revainrating 4 out of 5

NOT FOR BUFFER TUBE!

This wrench is NOT suitable for castellated buffer tube nuts. Not without some modification to the key itself. I bought this because I couldn't find my armor key and needed to finish the build. It did not fit. Had to sand down the center and back lip to make it work. Not everyone will have this opportunity. Now for the positive. If you're willing to make a few changes, it's clearly worth the money. But as seen in the picture, it does not work with the buffer tube castellated nut.

Pros
  • Excellent All-Round Performance
Cons
