I don't see it on Franklin Armory's website, but I did find a blurry photo from SHOT on their facebook page:
People have posted questions about price and availability, 'They'll be here soon" is what Franklin Armory says. As GTPprix says, you can see the H&K with a metal semi-marked housing, and you can see the switch in the full-auto position. Very interesting!
As far as AR's go, yeah, the Fostech Echo requires a proprietary bolt carrier, but had the advantage of being a drop-in pack vs. Franklin's Binary Fire System which required a more involved installation. I guess the Franklin BFS doesn't require a unique bolt-carrier because they only have 1 sear. It's my understanding the Fostech Echo has a secondary sear which prevents the hammer from following when the trigger is being pulled quickly during enthusiastic mag-dumps. The 3rd gen BFS has had some changes made to help prevent this from happening, but doesn't have a sure-fire way to prevent it from happening, and that said, from what I've read out-running the hammer on the BFS 3rd gen is now more-or-less a non-issue. I've never used either system, but I've been following both for awhile now.
There was an older thread where the possibility of either Franklin or Fostech making a binary firing system compatible with H&K's was discussed before any formal announcement was made. At the time it was speculated that Franklin would develop a system for H&K roller-locks & clones, and Fostech would be producing a system for AK's. The thread can be found here:

Hopefully the BFS III being made for the roller-lock system is just a drop-in pack! Not sure if it'll be compatible with only SEF housings or also with Ambi. Time will tell I guess : ) Either way, I think this is
very good news. Some people have knocked them as being a gimmick or unreliable, but I think they look like a great way to have some serious range fun for those that can't shell out for a real MG. If anyone else has any details, I'd love to know.
