its to op it takes one burst to kill and its not even fair

Very well rounded gun, the 1 burst up close is perfectly fine. any gun with the burst attachment is a 1 burst so it makes sense. However, the MSBS has a 1 burst long range chest up with the muzzle break attachment making it the fastest killing gun across the map. However It's hard to hit a 1 long range chest up on a moving target. In this situation missing the 1 burst long range would be deadly and you could easily get outgunned by any assault rifle, besides the honey badger and the ARx due to recoil at long range. In my opinion it's a well rounded gun but the instant kill at close range could be quite annoying. It's overall a well rounded weapon but it's instant kill at close range is the reason It's banned in competition.
