DIY AR-15 Barrel nut wrench.

Very cool. I really like the idea of welding the socket to it, cheap and easy way to make the square precise.

Thanks, I was also worried that over time use might loosen up the square for the wrench without it being hardened metal. Maybe over doing it though. I doubt in the life of the wrench it would see enough use to do it though. I'm probably gonna wire wheel off the jb weld too and have my buddy spot weld them In place.
