Keep in mind that airsoft isn't as accurate as real guns. You can have a gun zeroed to the n'th degree but you will always have to readjust something or other. Try using heavier BBs like .25 or .28 and see what the results are with those. Also sights integrated into the gun itself have a record of being HORRIBLE. G36s, P90s, TAR21s etc... all have been known to have shitty sights. Your best bet is to get a conversion for a top rail and get your own sight, one of a higher caliber of quality.
My trust is in whiskey, in weed and in Slayer, its GODDAMN ELECTRIC
