Question about Schiessbecher Kar98

Hi guys, I can’t find answer to this anywhere, but is the Schiessbecher Kar98 Grenade Launcher affected by perks for weapon changing speed (for putting it on). Additionally is it affected by reload speed and grenade throw distance perks?
Thanks

Not sure, but I also find this info is somehow lacking.

This not only for this specific weapon, but in general, including also upgrading of other weapons. For example, I wasted a lot of weapons orders to get enough Panzerbüchse 38 to upgrade one to the highest level, only to then find out that even though “hit points” increased by 15% as indicated, the actual armor piercing doesn’t change at all.

So how can a bullet get more hit power on one hand, but not get better at doing its job?

Would really help if those tooltips would not only show “this’ndat imrpoved by 15%”, but would show all the affected values precicely…

On the logistics screen for weapons, there is a little Grey question mark in the upper-right corner; if you click on that you can look at the stats of the weapon at each stage of upgrade. It’s a nice feature that is too hidden. It would be nice if you could see it from the soldier weapon menu also
