Colovance's Duty hits harder and is much more effective at longer ranges. Mida shoots fast and makes you run faster and also does alright in close ranges. In my opinion colovance beats it only because it is more effective in long ranges and the fact that Mida isn't the best in the ranges that colovance can't cover. Use mida if you wanna run fast and use a scout rifle that does well at long ranges alright at medium and not bad at close. Use colovance's duty if you wanna have a scout rifle that counters snipers beats almost anything at long range does alright in medium (if you land your shots) and is absolute sh*t at close range. Also Colovance's Duty is a 3 shot Mida is a 4 shot My personal choice is Colovance's Duty The roll on my Colovance's Duty is crowdcontrol, handlaid stock, and third eye
