Trivia
Although the MR-B is fictitious, it appears to be based on the Magpul PDR, a prototype/concept bullpup compact weapon designed by the same designers as the ACR (Masada) to be a more potent alternative to a submachine gun that would be used primarily by support troops that would normally only carry a pistol.
