Is there any way to help with the sniper rifle kickback?

Question

In RAGE, is there an add-on of sorts for the sniper rifle to help with the crazy kickback when the gun is shot while fully zoomed? If so, can it be built or purchased somewhere? I noticed other add-ons for the shotgun, and the sniper rifle does get a loading mod.

I was able to luck my way through the first Job Board sniper mission in Wellspring, but am having trouble getting through the next one with the caravan.

Answer

I've finished the game (not at the 100% achievement level) and the only Sniper Rifle modification I've seen is the semi-auto.

The RAGE Wikia says that the only modification is the semi-auto upgrade.

Do any of the unlocks modify the sniper's mortar strike?

Question

The sniper's mortar strike is a favorite of mine, and I was wondering if any of the unlocks upgrade it. For instance, there are unlocks for more missiles, ammo, or grenades.

Are there any that reduce the cooldown time, give you a second mortar strike, or increase the damage/size of the mortar strike?

Answer

I am pretty sure demolition spec improves mortar strike damage by 25% as well.
