Laser Rifle ignore psycho an Toughness and do 49 base damages on critical bypass (multiplie by 3 to 8 for final critt dams).
So if the guy have a Tesla ok you are screwed (you still do 0-3) , your only way to do something is critical bypass, but for a sniper, don't think it's that hard ...
On the other hand, even with a x3 critical you kill almost anybody 147 dam for the worst crit in the torso, i'd really like to do so, even only once per 10 shot ...
Maybe laser sniper should simply not use Finesse to avoid the 100dr (but anyway bypass ignore finesse ...), and this is maybe why you have issues, since apparently players don't know how finesse work (Atom fixed the minds on another topic about that)
