whats a good pri / secondary weapon for a end game?

for melee im currently using orthos prime (afaik thats the only prime i have and working, the rest are all parts...)

along with a price tag, would be nice for me to roughly gauge!

boltor prime is generally considered the best primary in the game.

other top tier primaries include soma prime, paris prime, dread, opticor, hek, tonkor

top tier secondaries include vaykor marelok, synoid gammacor, lex prime, brakk, atomos, and a few others

If you want to go full retard and kill every monster without proper aiming - take Amprex.
For a secondary weapon I would recommend Hikou Prime, they are awesome xd
