so, the salvaged weapons the callistans have access to are... Well very strong. From the player perspective that's not so bad, you need a bunch of research and to successfully fend off and salvage mechanoid attacks to get access to them, Gating them behind time and resources.

The problem comes from the callistan factions that spawn. I'm finding that The groups of callistan raiders seem to consistently spawn with these weapons far too early for me to have a proper answer for. they have a higher range, are harder hitting and also more accurate than nearly every gun you'll see on other raid groups at that game stage and unless I b-line for high end weapon techs or the callistan techs themselves it feels like I'm completely outmatched because of it.
