I've been gone a while. Got from 35-40 rather quickly before the weekend n spend time with my girl so I missed out on boost to 41(meh)

I was VERY FORTUNATE and grateful to have received the flame throwing carbine from someone in Phoenix randomly(since I'm guildless n don't know him/her at all). I was wondering if any other weapons have any special properties that might benefit my Engineer? I'm specced similar to NEWTS DPS still, will have to research any changes but so far in playing, none.
