What the weapon stats mean/do exactly.

[WyvernRock]

I've come to realise I don't fully understand what the stats of a weapon do/are exactly, so want to check what everyone else knows.

Durability - Nothing. I'm guessing this could be a feature in the future, so lets ignore this.
Recoil. - The lower this number is, the lower recoil of the weapon.
Ergonomics - I *think* the higher this is the longer I can aim down sights. Can someone confirm?
Accuracy - Not remotely sure, I don't know what "mrad" stands for, I think the lower this is, the more accurate the bullet is as I don't think this is impacted by recoil, just the bullets.
Sighting Range - I don't have a clue, is this the overall effective range of the weapon?
Muzzle velocity - Same as above, I don't fully understand this stat, I also can't work out what m/h is. Is this meter per hour?

Durability is currently not implemented, yeah.

Recoil is best compared to itself. if you modify a weapon and that number changes, that does mean something. Two exceptions: Kriss Vector has special recoil-reduction system and the recoil value is basically zero; AK74 can reach near 0 "recoil" but basically the actual recoil is about the same from 25 to 0. "True recoil" is represented in two things: shake and muzzle climb. Some guns have significant climb but no shake (such as MP5), while some has lots of shake but nearly no climb (such as highly modified AK74)

Ergo effects "true ergo" which according to dev themselves, is the combined result of:
1. Ergo value
2. weapon weight
3. weapon length
4. some attachments have hidden buff such as FSR2 angled foregrip
True ergo in turn affects two things:
1. how long you can aim down sight
2. how fast you switch between aim/not aim down sight.

accuracy is weapon's "spread". mrad is miliradian (1/1000 of one radian)

Sighting range: ignore it.

Muzzle velocity is in m/s but it say m/h. aside from bullet speed it also very slightly affect damage.

I would note muzzle velocity affects bullet drop and how much you need to compensate at range. I had a similar confusion wondering if if recoil was measured realistically or video game style: meaning is a lower value better (real) or is a higher number mean more favorable stat (game style). I've unfortunately played a good amount of games that use higher value as more positive even if it's an attribute where lower is better.
