Step 9: press scrap and modify at the same time on the missile launcher and immediantly flick your mouse to where the glitched shotgun is located 1 space down (this may take a few tries to get the timing right)
Step 10: if you timed this correctly you should be on the glitched screen and your mouse should be hovering over and highlighting the targeting computer slot of the missile launcher

Step 11: rename the rapid fire missile shotgun to whatever you like and have fun with this insane weapon.
Fun fact this shotgun fires 8 missiles at once and has a 32 round drum mag which means it fires 256 missiles in 1 mag dump!
