Shotgun bead sight

Hey guys, I messed up and over tightened my bead sight on a 18.5 in barrel, Stripped the threads on the barrel itself. My question is should I take it and get the hole tapped for 30-40$ or just use a drop of jb weld and let it cure for a few days. The hole for the sight is covered by the choke tube so would it would not be exposed to pressure. What do you guys think.
