im not sure about the dots extending ur range, like u suggested red. i really wouldnt bet on a red dot silencer to go farther than a plain gun.
im almost positive that silencers not only reduce range, but also damage. i like the idea of silencers, but not if it sacrifices 2 key elements.
Of course I know silencers reduce range, but I was saying that the Holo + Silencer might actually bring the range back up to normal. If it is so, then you now have a silent gun that can still pick people off at a distance. Whether or not it actually does that, I'm not sure, but I feel like it does. Try it out for yourself.
My game is largely based on the element of surprise, speed & accuracy. A silenced accurate gun serves me well. Thus, my <3ing of the UMP/SCAR/M16.
