According to the research we've already done and then timing of the release of other guns, it would appear this was an early NX Rare version of the M4. It was introduced into the game coding a couple years back. As the article says, it was most likely scrapped and replaced by the SOPMOD. However, that doesn't explain why it's been left in the game coding for so long... It's kind of a fun little thing to think about
