So, now that I have my Ohin Buster 50, I'm looking at the area on the back/top where an attachement might go, it's definitely made so something could be attached there, likely the attachment would also connect where the Vistamps go on the Buster as there's no buttons in the attachment spot to tell the Ohin Buster that something was connected, nor any post to tell an attachment that it was attached.

The IR communication with the Vistamps is great. And it's possible whatever is being made to attach to this might also replace the stamp thing that's the gun's 'barrel' too, making it the centerpiece of a larger weapon.
