Semi-automatic allows for players to easily conserve ammunition while firing upon weaker specimens and to maintain overall accuracy. The selective fire on the MKb allows a player optional control over the rate of fire. This increases the active damage per second output by 48% and 85% for after reload, resulting 688.6 damage per second for before reload performance and 425 damage per second for after reload. As a level 5 or 6 commando, the total damage output of a single magazine of 37 bullets is 2479 damage in 3.6 seconds with a 2.22 second delay for reloading before being able to fire again. This makes the before reload offperk performance to 465.5 damage per second and after reload performance to 228.8 damage per second. Without perk bonuses, the damage output of a single magazine is 1350 damage in 2.9 seconds (29 delays between 30 bullets), followed by a 3-second delay to reload. While operating at fully-automatic, the rate of fire for the MKb is 10 bullets per second making the fire rate once per 0.1 second. It has a rate of fire equal to the Bullpup, which is faster than the AK-47, and a bullet spread that is slightly wider than that of the bullpup, and narrower than that of the AK-47. Of the available assault and battle rifles, the MKb comes in the middle in the aspects of damage and ammo capacity, along with the AK-47. The MKb can decapitate a weaker specimen with a single headshot under all circumstances. At level 3 and above, commandos receive a 25% capacity increase, which does not divide well into the default 30-bullet capacity because it would leave the MKb with 37.5 bullets per magazine the result is a 37-bullet magazine and 375 total bullets, costing £125 altogether. At level 2, players receive a 36-bullet magazine and a 360-bullet capacity, costing £120 total. At level 1, players receive a 33-bullet magazine and 330-bullet capacity, costing £110 total. With another perk selected or with level 0 commando players get the default 30-bullet magazine and 300-bullet capacity, with a cost of £10 per magazine and £100 total.

The cost of ammunition remains static per-bullet at £1 for 3 bullets, but the magazine size changes according to a commando's level. The cost of the MKb42 is £1100, which can be reduced to £330 with use of the commando perk, at intervals of £110 per level. The commando perk gives bonuses and discounts on the MKb42.
