It's a relief for Dun, a far bigger one than he's willing to admit to himself even, to know that the salarian didn't mind offering advice. Even better is that he didn't prod too much into Dun's personal life and history either. A quick look at the display of firearms and Dun points out one in particular that he hasn't really seen in action yet: a sniping rifle.

"I haven't seen any of the mercenaries using this one. What sort of gun is it?"

It's long body meant that it would be cumbersome to carry around. It didn't look like it'd be good in a close range fight, and it'd be difficult to move from one position to another with it too.

It doesn't seem particularly useful.
