Weapon choice. Can't decide between KA-101 or AUR-A1 as secondary with DMR as primary.

Title says it all. I have a DMR as main long range rifle. Currently I have a AUR-A1 with 2 mags and a KA-101 with 2 mags. I hate triple carrying and can't decide which to drop. I'll mainly use it for CQB because, well DMR... Also have Fx-45 with silencer for Z's.

The AUR is supposed to be more nimble, but I'm really in doubt.

Any considerations? Thanks
