You don't need "accuracy" upgrades if you're playing CQB. Sure I could see it for a larger outdoor field where you're pretty much firing at your maximum effective range when you're engaging however in CQB you're like 10' away from your target. A 1/2 inch grouping better at your maximum effective range translates to nothing when you're firing at CQB distances.
If it's for indoor and outdoor I'd really suggest getting an indoor gun and an outdoor gun. Since that means you open up your mechbox less AND have a smaller chance of fucking something up when you're switching springs.
