It's like the rear site is welded into the dovetail or there's a set screw locking it in place. It will not budge! It needs to drift to the left. I tried moving it in the past with no luck. But I really wanted to get the job done this time. I removed the barrel from the stock so I could really clamp it tight. No matter how much force I used hammering with the brass punch... nothing. Then I thought maybe there's loctite on it. So I took my heat gun and got the barrel hot. Too hot to touch. Still nothing. Then I got an ice cube out of the fridge and heated up the barrel again then applied the ice to just the site. The ice quickly melted and then steamed off (barrel must have been hotter than 212F). Hoping I expanded the dovetail metal a couple thousandth or so and then by shrinking the site metal maybe that would let me drift it. Again, zero movement. You could imagine I was really smacking that punch to rule out timidness on my part.
I bought this factory new. I'm the only owner. Videos on youtube show guys easily drifting their sites or removing them altogether to upgrade them. Also, my front site does drift. No shenanigans required. It's just this dang rear site. I think there may be more going on than I'm aware of. What would you advise I do to drift the rear site on my rifle?
