What perks do you use with it? I usually use that one that fires faster(forgot name lol) and deep impact or stopping power i forgot I'm not exactly sure. I have bomb squad for perk 1, the second perk is the one that gives extra bullet damage, though I am trying to decide if bullet damage is worth giving up camo, and the third I believe is stopping power, just so I can have a better chance at killing someone behind a barrier. i think you mean stopping power for 2nd, and deep impact for 3rd and don't use double tap on m1, double tap only affects smgs and mgs
