BR has more aim assist then the carbine while carbine has next to none. I've been going over this scenario in my head.. Carbine Vs BR strafe-fest. Carbine is likely to lose as he has to keep his no-aim assist rifle reticule over a tiny head while the BR can just spray away because of its 3 shot burst and has aim assist backing it up. You can say I need to get better with the Carbine all you want, and quite honestly I'm working hard to learn this new wizardry, but everytime a strafe fight happens I just miss my shots ALOT, then end up getting picked off by them sweep headshoting.
