There are plenty of weapons in Armored Core 6 that require reloads, and most of the time, they will reload themselves automatically when the ammo runs out. However, those animations can take way too long at the worst times in a fight, and luckily there is a way to manually reload those when you want.
How to Manually Reload Weapons in AC6
To manually reload in Armored Core 6, you need to press Triangle/Y and R2/RT at the same time. The Shift Control button is what allows you to pick a specific weapon for reloading. On PlayStation and Xbox, that control is “Triangle/Y” by default. For keyboard and mouse players on PC, that same control is the “R” key. That only opens up the menu for reloads though.
