Yes, you can straighten them very carefully. The screw itself is rather thin. Maybe 1/8” diameter. I doubt you’ll find a replacement.
 
Might want to use heat depending, i would remove the screw from the gun, maybe thread on nuts if you can match the thread to hold it without damaging threads.
 
There's an app called 'thread pitch' by smart tools. Open it up and lay your screw on the phone screen and compare to the displayed zigzags. Also has a ruler function for length. Might help find a cheaper replacement
 
how did the screws get bent ? I think you would be wise to use a micrometer and a thread pitch guage to decide the dimension of the screws in case you need to replace them

Its very easy to straighten - use hardwood blocks, dowel and hammer. Report back...

Yep. This right here.

I am working on the idea that the heads are hula-hooping when turned, yes?
Drill a hole a bit smaller than the screw thread into a piece of wood, and thread the screw in to it as far as you can get it. Use a dowel, or a small piece of aluminum, and gently tap with a small hammer on the high side of the screw head. The wood will have enough give that even if you have the screw head right against it, it will move a bit.
If the screw is bent in the middle, lay it on a wood block and roll it to identify where the bend is. Set your dowel or piece of aluminum on the highest point of the bend, and give it a tap to straighten.

If you have a drill press, you can chuck up a dowel or piece of aluminum rod and use it as a press, with a block of wood under the screw as needed.

I can see where the screws are bent, it might be a bit of a problem to straighten it because it is a short screw, it ajusts the left and right of the scope, *windage * if i'm correct?

Good idea for the drill press.

Yeah, a drill press can be used as a light duty Arbor Press, if it's what you need to do. Gives you pretty good fine control of the pressure you apply. You do want something softer than the screw above and below the screw so it does not deform the threads worse than they already are. Even a couple layers of paper will work as a pad.

Chances are good that the reason the screws are bent is that they were horsed down too tight while someone 'adjusted' them. Be careful, snug them up, and use a non-permanent thread locker on them and you should be good.
