In this video I show how to make a spanner wrench for the castle nut on the buffer tube of an AR-15 rifle. I know you can buy a wrench fairly cheap, but since my local gun store was out of stock and I didn’t want to wait for mail order I decided to make my own. Besides, I like to build stuff myself so this was a good quick project.
