About to lose my mind

take the caps off the donny and switch them

A little OCD are we? ;^) You can put washers, shims or an o-ring between the moderator and barrel/shroud. Or maybe tighten the barrel nut a little if it is an FX product. I would probly have to do it myself cuz I"m just a little OCD.

So put my donny fl on and the logo is 180 degrees out. So on wrong side and upside down. Cant spin barrell bc it has flats on one side.

What thread size is it?

Unscrew the cap near the barrel. Take off the body of the suppressor. Flip ends then reinstall. 

after ya get the tube flipped around and the donny is back on the barrel, I put a removable pencil mark on the far end cap where I want the Donny logo to line up, loosen, adjust the sleeve to the mark, tighten back up

Looks like you got it figured for yourself and the rest of us as well.

There are no stupid questions. When it comes to this hobby/sport I have spent a fair amount of money and I want all my guns to look and shoot the best that they can.
