So I have a m4a1 and I'm just practicing using it the now. When I am prone however, my bullets seem to be hitting the ground directly in front of me instead of 200 m in the distance. When i crouch I have no problem. If it helps, my M4A1 layout: -Suppressor 556 (worn) -ATLAS Bipod (pristine) -ACOG Optics test (pristine) -M4 Buttstock CQB (pristine) -M4 Handguard MP (worn) -30Rnd STANAG (coupled) (pristine) P.S. I have tried the search function but could not find any similar problems, sorry if this is obvious!
