Cannot remove bolt catch detent.

[Zane1844]

I have been having problems with the bolt locking back before the last round- the last round will be in the mag- and I have changed the bolt catch, but I cannot get the detent out to change out it and the spring.

This is a factory S&W lower.

Any ways to get this thing out?

Soak it in Kroil overnight.

Wow, just got it. I sprayed a little break cleaner to get the area clean, then I just pushed it up and down really fast and it came right out. I am surprised that did not work before.
