Running a sniper rifle requires more than a simple spring/gearbox swap, and higher FPS does not equal better ballistic flight performance. What you're looking for is ballistic STABILITY - i.e., relatively flat trajectory over long distances with minimal horizontal drift due to crosswinds. Stable flight is achieved using long tightbore barrels, a good quality hop-up, a tight compression chamber/piston setup and heavy BBs. This should get you flight stability over the distance.
What a higher FPS will do, however, is allow the BB to travel further before gravitational effects start affecting the flight path. The backspin from the hop-up is to offset gravity by providing lift to the BB during flight.
Other equipment attached to the rifle - such as scopes, digital wind displays, bipods, zero/two-stage triggers, barrel stabilizers, etc. - will affect the accuracy of the firing platform (less drift, minimal trigger jerk, wind correction, etc.), but won't affect the flight itself.
And as others have already said - get yourself AV'ed. If you're 36, it's a painless process.
