I was about to upgrade my rifle weapons mastery and only just noticed the wording of the description...
"Are you sure you want to spend 10 merits on your Rifle Mastery upgrade? This upgrade will improve your proficiency with these weapons, increasing damage by 1% and accuracy by +0.2. Rifle weapons include: AK-47, Enfield SA-80, and ArmaLite M-15A4".
My question is do these upgrades apply exclusively to the mentioned weapons or are they just used as an example of what falls into the rifle category? The same logic applies for all the other weapon merit upgrades as well by the way.
