Yay. I'm content to the lengths of my curiosity, in 24 hours, everyone helped me figure it out. Thank you to all who helped.
This is here mostly for my own reference, as my mind goes a million miles a minute, I'm libel to forget something:
The Pflager-Katsumada Series D Blaster is available in several civilian models (because as a "Series," wouldn't there be more than one?), and the BR Special, reserved for Law Enforcement.
Chambered for 11mm rounds.
The Civilian versions are also electromagnetically enhanced, but not to the extent as the BR Special, just enough to increase accuracy. (The BR Special's Electromagnets not only increase accuracy, but speed and power as well, not to mention explosive headed rounds.)
The Civilian versions don't have the "Sonic Shock" (taser-esque, borrowing the name from a different idea of someone else's) feature, and the bolt is just to charge the magnetic assist. No battery pack either, just a removable hollow chamber to store more rounds.
Electromagnetic Housing (Rifle Receiver) built by Steyr-Daimler-Puch for PKC (thus explaining those markings).
(But don't stop here, I like to hear everyone's versions/opinions
)
Even updated my poster to accommodate my changes in ideas and perceptions about it.
PKC idea as a company and the appropriate logo shamelessly borrowed from Rick Ross' website. But it's ok, as long as it's all good fun, right? And I don't intend on selling any blasters under the PKC name, I'm not like that.
Brownie points if you figure out what all the Model Names mean.
But who knows, I may change this all yet again...
