I purchased the Bullseye pack to get some achievements and the resistor mod wasn’t in there (which is needed for an achievement and is only in the Champion’s Bundle). I did some looking around and 343 is supposed to release it to everyone at a later time. Is it still coming or has it been forgotten? 
EDIT:
Also, is there any chance we will see a DLC only playlist? I have quite a few achievements to go and I haven’t seen a DLC map all day.
No news yet. 343i hasn’t said anything about it since the Bundle was released.

In response to your DLC playlist question, here is a post I made in another thread regarding this:
> An ALL DLC playlist is impossible to make because the DLC maps all require different team sizes. Because of the BTB maps in both the Crimson and Castle map packs, the minimum team size for an all DLC playlist would have to be 6v6. This wont happen because the Majestic and Champions maps are made for 4v4 or FFA gametypes. You CANNOT play 6v6, 7v7 or 8v8 on maps designed for 4v4 or FFA play as they are too small, the game would be uplayable (spawn camping/killing) and wont properly accommodate 2 teams of 8.

> And before anyone says “just make 2 playlists, 1 for 4v4 and the other for BTB”, there isn’t enough hopper space in the matchmaking server to do this, not to mention that the population would be divided even further than it already is which causes longer search times in the playlists. Plus its a known fact that DLC playlists are hardly ever populated after the initial release of each map pack, and as such 343 removes them, as they are considered dead and take up space that could be used to improve matchmaking quality.
