With the advent of Revelations T2 snipers have been reduced to being more in line with T1 snipers as far as range and damage are concerned. This is a fairly standard sniper fitting, although the spare two highs are fairly modular, along with one of the Tracking Computers and the Medium Armor Reperair. Switch Medium Armor Repairer to a Small Armor Repairer and use a Reactor Control Unit if your fitting skills are bad.
