I'm hoping the content of your other post is an indication that there is more in the works, but with more flexibility and modularity. I would think with Mossbergs presence in LE and military that something like that would be the next natural eveolutionary step. Much like the SBS (compact cruisers), a carbine length or restricted AR platform, but also barrels and options to make it available to the public. Especially if its all compatible with any other M4/AR parts available on the market.
Yeah, that would be cool...
