Heres a question, why use a flashlight on a sniper...
No1 posted anything about a flashlight on a sniper. Someone posted about a FLASH SUPPRESOR. Now that's better. Flashlight on a sniper is really dumb, just like putting a rifle scope on a shotgun while you have buckshot.
attachments are kinda random. I like flashlights because they piss some people off xD but I mainly use Kobra RDS and PKS-07 as optical attachments.
but heavy barrel and suppressor can always be useful and fun.
I prefer close contact with enemy so I chose knife and pistol combats if possible. But my favorite weapon is RPK-74M (18 service star) with foregrip, flash suppressor and ACOG x4 while playing as support, additionally AKS-74u, same attachments, while playing as engineer. I also love C4 on tanks :-)

The guns above used in Hardcore are superb. Little to no recoil, Most of the Support Class guns take 2 bullets to kill a person, and the rest take 4-5 bullets but are still quick enough to kill the other person before they kill you.
