Works as it should

I bought this because I was putting together an upper receiver for an AR-15 and the flash hider needed to be timed. I was not able to tighten it enough by hand, but this did the trick. I also used it for a few other things. It did the trick for the barrel nut, and it worked for the castle nut on a different rifle. I bought it from here because this was the best priced one I could find, and I don't tend to have quality issues from BUDK.
