Something I would definitely recommend is to collect every single collectable on the map.
You get 11000xp for each Phone/Drone/Survival guide/Laptop/Echo/etc which means, if you’re level 30, you will get a crate every 4 collectables.
Even if you don’t get any good drops, you’ll rake in the cash and can spend it on the boxes @Leepants does that get you Pheonix credits.
In addition to this, give the ‘named boss map’ a google and do a run on those guys at a higher level. A few of us did a full run on the non-Dark Zone named bosses at tier 5 and were getting loads of Gold and Green drops with a few Epics sprinkled in.
If you can survive the extraction, doing a survival run wouldn’t hurt either - I got my SRS and a few other bits from the last one I did and haven’t been able to find anything better since.
@Leepants is the fountain of knowledge though so it might be worth pecking his head for some tips on gear levelling or at the very least do some runs with him, he’s a proper generous bugger with his gear and will drop anything and everything he doesn’t need.
