Welp, better hope that RAC2 has enough of a punch to make it a primary light/medium mech weapon on its own. Otherwise it's still gonna be rough to make much use of ballistics below about 50 tons.
Heavy Machine guns are post civil war. For the IS. 3068. So, I'd say it's not a hard fast "3067 or earlier".
