I'm wanting to change the front sight on my 1980s T/C .50 Renegade, but try as I might, I can't seem to get it to budge even a little bit, punching left to right. I soaked it in penetrating oil but no luck. I don't want to beat the tar out of it and booger it up. Maybe soak it a day or two in penetrating oil? Any suggestions? Anyone else had a problem removing Renegade front sight?
