To be fair the best assault rifles at the moment are the SG 550 (Soon to be the SG 552 IIRC) and the M4A1. As it says so in the description of the SG it is a burst firing beast which really lives up to it's name in CQB. It may sound shit (It honestly does lol) but got quite the punch and can kill easily anyone with 1 burst, even armored targets. If you're not a fan of burst fire there is always the spray and pray and accuracy beast M4A1. gg
