Shockingly enough, the all-knowing Google had nothing....
Considering they are an AR maker, likely something AR related. I'm thinking a caliber quick-change system for AR15. There's not a whole lot to do with the AR platform that's 'revolutionary'....and I can't see DPMS trying to design a new system ala SCAR/ACR, especially without a peep getting out to the community.
Of course, if Remington and DPMS are still owned by the same company, it could be a DPMS version of the ACR....
It better be something interesting. I'm bored with ARs. Good thing I just bit the bullet and picked up a SCAR 16s. That should keep me entertained for a while... until I get the uncontrollable urge to buy a Tavor or something.
