Change gloves to assault if you prefer lightweight m4. u use house because i play pc and is full of strikers with good movement and m4 is already difficult enough to control so i recommend house. Addition to that get porotype mods that get crit chance. Responsive/fierce/adept can replace competent. This is a min max build so for new players, just stack crit chance/damage as much as possible. i use recon pulse for the range and is not really any different than tactical scanner.
