For what its worth, I personally wish scopes were a more reasonable option for aesthetic reasons: they just look cooler. But the designers of SR4 went with the simple "vision magnification makes all ranges Short," instead of messing about with degress of magnification. Maybe house rule it so that Scopes give a few bonus dice if you Take Aim?
I had house rules for SR3 that enabled rifles to exceed their presumptive maximum range. If a Barrett .50 M82A1 can deliver lethal hits at 2300m, and others at 2500m and beyond, then SR's 1500m extreme range is clearly in need of ... not revising, but extending the table if you have the proper gear to do so.
It took a complex action for each additional range bracket, and you could only extend it to the rating of your scope (i.e. up to a max of Extreme-3); target numbers were still equivalent to Range Bracket - Rating, which meant if you were shooting at something at EX-2 and you had a level 3 scope, you had the TN equivalent of Long Range.
I also expanded the 'grades' of rifles; sporting rifles don't shoot as far as the ones snipers on SWAT teams do; those don't shoot out as accurately as the sniper rifles the military uses. And of course,
everyone knows that the CIA has guns that can kill you from, like, five kilometers away, right? Therefore Sport, SWAT, Sniper, and Sanction grades were 'born'. (And no, you did NOT want to become the target of a CIA hitter using a Barrett M135A5 ...)
