What up all (new to this site):
I have a new build but there is a gap between the mod and the atty. The Dingo comes with a 510 pole screw that normally comes with an o-ring sleeved under its head. However it didn't come that way, rather in a separate parts bag. Instructions say to remove that o-ring but again not there. Please see pics below. Any ideas? Thanks in advance! mods, please feel free to move this to the proper sub forum if you deem necessary. Thanks again.
First my new rig!

Now a few pics of the gap between
