I logged back into valorant after a very long time (from beta) and found some new interesting features...
One of this was the "easiest" to spot: the weapons statistics on the shop.
This is a small thing, it says what kind of weapon you're shooting with:
Automatic
Semi automatic

But actually, in the operator animation you can see the hand bringing the Bolt back sliding with the bolt handle.
That kind of weapon is called bolt action and it's quite slow (that's why you usually swap twice the weapon to skip that animation)
