So I went to install a new precision barrel, and ran into a slight issue. Stag used a slim barrel nut on the rifle and I don't have a tool that fits it. I either need some help to break it free, or help finding a good gunsmith around Denver/Reamstown area. I work in Plymouth Meeting so anywhere in between (Exton) would be okay too.

Here is the nut that Stag used: https://www.stngrusa.com/collections...el-nut-ar15-m4
