Don't wanna rain on anyone's parade, but this has been suggested years ago, canam replied "we'll look into it" and still isn't reality, so I guess they looked into it and don't believe it would be profitable, so I doubt it's in the cards:

Since the first thread, thousands of BCL102/STAG10/Matrix have been sold, and canam has replenished their stock or AR15-DA50, so I guess they don't see profits in making them for the multitude of 102 lowers that are around.
If someone has the tooling however, they could buy the stock of "gunsmith special" barrels and run with the project. Maybe a more "boutique" shop would be better positioned to make this a profitable project. YMMV.
