Archived [ARCHIVED THREAD] - RRA serial numbers
Posted: 4/24/2005 7:05:34 PM EDT
I recently looked at a RRA lower.  The serial number began with CM.  Does this have something to do with who actually made the lower?  I did a  search for info on this and came up dry.  Thanks for the help.

All their rifles start with CM, and their pistols start with RA.

Thank you Sir, I wasn't sure if it signified anything or was just a prefix.

I thought CM in front of the Ser. # Stood for CMT (who actually made them)

CM stands for Continental Machine---the outfit that has always made Rock River's lowers. They also make the Stag and Century Arms lowers; and those lowers are also marked "CM" ahead of the serial numbers.

HA!  Learn something new every day!  I never really thought about the CM on my 2 lowers...
