Sniper rifle mod

There are five types of mod for sniper rifles, each providing a different benefit. For each type, there is one basic mod and two upgrades which provide a greater benefit, but with detrimental effects. Only the basic mods are available at the first tier in singleplayer.

Barrel

 * SR Barrel: Enhances a weapon's barrel, creating greater gunfire velocity and impact.
 * SR Reinforced Barrel: Substantially increases damage, but at the cost of increased recoil.
 * SR Vented Barrel: Substantially increases damage, but at the cost of fire rate.

Clip

 * SR Spare Thermal Clip: Adds sockets to increase thermal clip capacity, increasing number of spare shots.
 * SR Heavy Spare Clip: Substantially increases spare ammo, but at the cost of increased weapon weight.
 * SR Light Spare Clip: Substantially increases spare ammo, but at the cost of accuracy.

The Inferno and Shadow cannot be equipped with a spare clip.

Materials

 * SR Ultra-Light Materials: Superior lightweight alloys replace weapon parts, making the weapon less obtrusive and easier to handle.
 * SR Experimental Materials: Substantially reduces weapon weight, but at the cost of increased recoil.
 * SR Latticed Materials: Substantially reduces weapon weight, but at the cost of decreased clip size.

Receiver

 * SR Receiver: Capacitor boosts kinetic coil generators, increasing shot penetration through solid objects.

Scope
The SR Tactical Scope VIII is incorrectly named as SR Tactical Scope IX but can be distinguished from the real SR Tactical Scope IX by looking at the stats.
 * SR Scope: Simple optical scope to enhance stability while zoomed. Also increases accuracy while moving.
 * SR Recon Scope: Substantially increases accuracy, but at the cost of increased recoil.
 * SR Tactical Scope: Substantially increases accuracy, but at the cost of increased weight.
