Re: Exactly what gun upgrades can you get playing solo battlefield 2042?

I appreciate all of the answers. So my understanding is that when you first use a weapon, you have zero kills. You have to kill a certain amount (5-10 in most cases) of enemies to reach Mastery 1. The upgrades that require kills of less than Mastery 1 are accessible by playing solo. However, killing a bot does not count as a kill.. so there is no progress made on your Mastery 1 of that weapon. I noticed most every upgrade, but the first sight required at least a Mastery 1. Meaning a person can only (in most cases) open one of the sight upgrades by playing solo or multi-player against the bots. If it had to be just one upgrade.. that would be my pick. My iron sight game is weak. :/
