The ME-262 has very poor gun performances which require excessive lead with the MK-108. early ME-262 V prototypes where fitted with MG-151 instead of MK-108s which the MG-151 is far easier to lead this option will be available to all models of 262 in game other than the 50MM and sqaudron 262 models which have different noses
in game this will be a similar swap to the BF109 K4 weapon selector you go to modifications and select the MG-151s and it removes the MK-108
