You are only going to get one shot at this, so take the time required to get it right. Mount the gun in a gun vise so it won’t slip. Select an Allen bit that is in good shape without rounded or worn edges. Make sure the hex pocket in the screw head is clean and free from debris so the bit can enter all the way to the bottom. Insert the bit into the screw and tap it into place with a plastic-tipped hammer. A few solid whacks with the hammer on the screwdriver handle not only seats the Allen bit in the screw, but may also help loosen the screw. If the fit is at all sloppy, put a little Drive Grip or powdered rosin on the bit. Using two hands, push straight down on the top of the screwdriver with one hand, and turn with the other. Keep the screwdriver perfectly in line with the center of the screw; do not allow it to tip. Be careful about how much torque you apply, as these are small, rather delicate, screws. If the screw doesn’t loosen, back off. Try again while tapping on the screwdriver handle with a plastic hammer and applying constant torque to the handle. This is easier if you have some help. One person taps on the handle with the hammer, while the other keeps the screwdriver straight and applies the torque.

If just one of the screws is a problem, remove the rest of them first. Sometimes there is a misalignment of parts, so that puts pressure on one particular scew when all of them are tight. Removing the rest of them will often relieve that pressure, allowing the last screw to be removed.

If the screw is in a scope base that sits on a flat receiver, you can sometimes use a plastic hammer to tap on the base and turn it on the gun enough to loosen the screw. Remove all the other screws, and then tap the corner of the base so that it will drive the base counter-clockwise. It’s not necessary to turn it very far—just a partial turn will often break the screw free. Sometimes working the base back and forth with the hammer a few times will also break the screw free. Be careful about doing this on rounded receivers like the Remington 700, as tapping the mount will cam it against the receiver, jamming the screw tighter or breaking it off.

I found the entire article to be very helpful.  Yes, the value of torque wrenches, quality gunsmithing tools, and gunsmithing screwdrivers cannot be overstated.  You know all of those screws on lever action rifles?  Yea those.

You don’t get them off with a regular screwdriver bought at Lowe’s.  Quality gunsmithing tools cost more, but it’s worth it in the long run from damages to your firearms when you use the wrong tools.

I’m not being a know-it-all.  Like all good engineers, I learn by doing it wrong the first time.
