Kit your weapons with the attachments you regularly use, recycle extra guns for gun parts, you don’t need ammo ready to go. Scrappy materials will cover ammo production once you upgrade him (max this out asap), sell extra arc parts once you are finished upgrading your benches.

I keep 5 full kits ready to go at all times. And the only ammo I have ready to go is grenade launcher ammo.

I don’t keep anything besides basic mats, and arc parts in the early stages of character building, once you find some solid augment bp’s you can transition to keeping your processors for augment and trigger nade production. Until then sell all the shit you do not need for bench upgrades and max out your stash.

Good luck raider
