Replace mpt 76 with mpt 55

[batubbal]

With the ico update, especially in close combat, the blur effect arising in the pressure shot has become a severe disadvantage for those who use the battle rifle. It is really difficult to both set up a pressure shot and hold the target, but when there is a weapon using 5x56, things get more comfortable, at least you can hold the weapon and it is even more comfortable to point the weapon at your enemy, but this is really difficult in the battle rifle, so please replace the mpt 76s with mpt 55s while you are still at the beginning of the work.

The 76 is supposed to have higher dmg but I need 3-4 shots in the upper chest to take down a guy. And because of the recoil you can just optimize it or limit the 76 down to 2 per Squad while the rest got 55s.
