Also be sure to tek your weapons correctly.
A 5 or 10 should never be on a correctly tekked weapon.
A correctly tekked weapon will increase in all areas where it has stats 10 points, say you have a 5/0/25/0 weapon untekked, it would have 15/0/35/0 when tekked correctly. It can also fall 10 points in all available stats so watch out for that too.
