Good question. I'm kind of curious about that. They all have different ranges that are separate from the range stat (that only has to do with projectile speed). That's just what I've heard, BTW. I always assumed you'd get better range with the range stat high because the projectiles would travel further before the damage drop off started. Anyhow, my Thesan can consistently kill guardians at midrange and I use it to fight bosses from sniper range. If anything is better than that, I'd definitely like to see it. [spoiler]For the record, that Thesan has Rangefinder, Hot Swap, and Braced Frame. That means it has tons of ADS range and max stability. [/spoiler]
