I stopped using that thing after 3 rounds, SMG outshooting every AR, don't even need to ADS unless you want to challenge DMRs midrange or the rare bipodded LMG.
On a side note, i guess we found out why guns (to me at least) feel a little "off" in BF3 portal, they're using the same recoil mechanics (which is why the G3 feels very off in single shot mode and has comedy accuracy on FA vs the "original").
Even the AN has much worse mid to long range accuracy on 2-round burst, even if it's a little better than the G3 in that regard.
