What are you using

Is the gun configured say grabbable is on

Connect the body of the clamp to the trigger handle

Which is basically the black block

I assume you froze the gun handle

If you did unfreeze it before you attach the black part

Then do it

If you miss connecting the gun handle at the right time and it falls, just disconnect it and move it back to the right position, place a block under it, and try again

Unfreeze then connect clamp, then if you want to, freezen it to continue working
