Okay. I give up. What’s the difference between Barrett’s M468 and Barrett’s M648?
They’re both assalt rifles chambered for the new 6.8 SPC cartridge, but everywhere I look the designations M468 and M648 seem to be used interchangeably.
(Actually, I’m almost willing to believe that there’s really no such thing as a Barrett M648. A google of Barrett’s own site turns up exactly zero pages referencing ‘M648’. But several well-known and respectable publications (most notably the magazine ‘Small Arms Review’) have information and/or articles on the M648. For years I’ve been hearing about the M468. Now lately it’s all been M648.)
Someone help out ol’ Murdoc.
