Since the latest major patch for Warzone, it appears more bugs and imbalances are appearing.
This time around, it's the shotgun attachment on the FR 5.56 assault rifle. The attachment can down an opponent in a single hit from over ten metres away.
Thankfully, Infinity Ward has already identified the issue and has begun working on a fix. Judging by how fast it took to fix the infamous polygon glitch, it could be a while before we see it implemented into the game.
Despite it being another frustrating imbalance to the weapon meta game, it does make a nice change from the endless use of the Bruen MK9 light machine gun which has dominated the metagame since the GRAU 5.56 assault rifle received a heavy nerf at the beginning of Season 5.
