You need to Rank your stuff to Max to increase your own Rank. With your own Rank higher you unlock a bunch of other weapons. So I'd recommend a bit of "grinding basic weapons" to increase your arsenal. Different weapons for different situations and such.
Also Mods make the difference. If you can get some Corrosive damage on those buggers it should help a bunch.
