1) Disintegrate. If you don't get this you don't get beam: There was no point. What are you even doing.
2) Piercing Beam. A Tier 3 blast. Except it slots as a Targeted AoE and can hit 3 targets in a very very thin cone (basically it's a line). Deals 1/3 more damage on disintegrating targets.
Now this would be a little end-intensive for other ATs to use for single-target but you're a blaster and you have a Sustain. Enjoy.
3) Single Shot. Better DPA and offers -regen against Disintegrated targets. Since you gotta pick at level 1... I pick it over Charged Shot every time.
4) Overcharge. It's your nuke. And it's ranged. If they ain't dead they're probably under Stun Mag 3.
5) Penetrating Ray: It be snipe. It can be instant under Aim. It be pending some nice buffs. Enjoy.
6) Lancer Shot: may soon be a source of Auto-Spread. It tends to Stun Mag 3. Tier 3, Mag 3, spread-to-3... Lancer Shot
7) Aim. Yup
