AR Rear Sight

[fishfighter]

what kind of sights do you guys have on your AR guns, i have the factory dpms rear peep sight and it is impossible to use in low light situations, i was out saturday afternoon and decided just to glance around at the end of "shooting hours" and could not get a visual on anything in my site, i couldn't even find my finger tip through that peep sight, i will probably just mount a 3-9x40 scope on it, but i haven't made up my mind yet cause i am not sure if the front sight will be an issue with a scope on the gun, i kind of like the open sights on it for close quarter shots, but i bought the gun for hog hunting day and night
