if BC2 i prefer all AR/SMG/LMG without optical sight, but in BF3, optical sights really helps me, well BF3 really did a good job in target acquisition. RDS or Holo works with me, and i never use that ACOG, 6x Scope, or whatsoever that magnify, i'm better with iron sight, HAHAHAHA

anyway, enough with sight, for accessories, laser sight is a must and a foregrip. even in real life, i tend to hold the rifle's magazine, HAHAHA, addition of foregrip, syok wooo
