For no better reason than “it exists”.
‘Course, I would “settle” for the production rifle it is modeled after, but something tells me that thing will not be imported any time soon, if ever. Supposedly accuracy can be down to 0.2 MOA (yes, that is zero-point-two), but magazine reviews indicate 0.75-0.5 MOA is not impossible (*.pdf warning).
In reality, the only thing we mere peons could probably procure is the airsoft clone I coincidentally stumbled across a few days ago, and I cannot even afford that.
(And, yes, I know there are far cheaper rifles that can do almost as good on the target paper, especially with me behind the trigger… That does not matter. Want.)
