Forum:Weapon for Adept

I've only being playing ME3 Multiplayer for a couple of weeks now, but I recently started playing a lot more Gold matches. I tend to play as an Adept, Sentinel or Vanguard - depending on the enemy. However, I am having trouble finding a suitable weapon for my Adept characters. I tend to travel light, and up until now an Avenger X served me well. But it just isn't competitive at Gold level. My other Assault rifles are either similarly useless (Phaeston, Vindicator) or not suitable to the Adept's style of play (Striker, Mattock). Any of the pistols or SMG's I've tried have too many flaws, and bringing a Sniper Rifle or Shotgun seems a bit counter-intuitive.

So, does anyone have a suggestion for a weapon (preferably automatic or fast-firing semi-automatic) that would suit an Adept well? I don't care how rare it is, as it will at least give me something to aim for - but if we could avoid the Ultra-rare category it would be nice :)
