Pile has Pile of a Problem.:(

V.A. removal

The last thing you want to do is use heat,
have you ever had to deal with a warped rail.
It can cause more problem's than you could
ever imagine. I've been a machinist for close to 20 yr's
I'm also a gunsmith on the side, that's why I
suggested an Impact Driver and "GOOD BRACING",
You don't want to tweek you're rail,it can cause so many problem's you would'nt believe.
But that's just my .02 cents
I'm still

Thank you, thank you, thank you Festus!!! I have been a mechanic for about 15 years, and I like to think I know a few things about frozen screws!!! I case you are not familiar with what we are talking about, we are talking about a Hand Impact Driver, available at just about any hardware, tool, or automotive store!! Also, make sure you are using an Allen socket and not an L key!!! L keyes slip off a lot easier and are more likely to strip the screw!!! And as Festus said, make sure you brace the adapter really well!!! Hope this helps!!!

I would try heat first. Not flame, just hot or boiling water. The amount of heat delivered won't warp the rail.

WD-40 is not a good penetrating oil. It is a good general purpose light lubricant. There are many good penetrating oils out there that will work though. Most of them are corrosive on some substances. Read the directions on the can.

Definately use a good, well fitting allen tool/socket that will allow you to get good pressure on the screw.
