Can anybody recommend where I can get a good Legendary Solar machine gun? Not from raids or dungeons please, I can’t do the higher level content (Maybe because I don’t have a nice machine gun, but probably because I don’t have friends or skillz) anyway, thanks bye.
I was gonna mention Fixed Odds since it's also craftable, but then you mentioned "no dungeons". Unwavering Duty is from trials, so it's probably also a no-go. Avalanche is sadly tied to the Christmas event. Iron Banner just ended, or you could've also tried for Archon's Thunder. The other reply mentioning the Thermal Erosion from Europa is probably your best bet.
Running the Lost Sector in the frozen zone on Europa once a day will give you one of the Europa weapons. I think there’s 6 of them, so shouldn’t take long to drop the LMG and it’s something super quick you can punch out when you log on :).
