im a bit unconventional. I normally go for a sniper gun. Not any sniper gun but the M24. It is currently in use by the US army. single shot with manual reload. Thats how a sniper gun should be.
If i have to use an assault rifle, I will use AN-94. Probably the best assault rifle made by the ruskies. I actually got to fire one in Phuket, Thailand. This baby is 'da bomb'. I dont like other rifles and never ever use OICW. The zoom is incredibly high for an assualt weapon.
But if im not in snipin mode i am equipped with MP5 with 4 sensors. MP5 rocks at close range but at longer range, u are dead meat.
And if i have to use a support weapon, i will use the FN M240G definitely. The best MG the world has known. even the US are dumping the m60 aka 'the pig' for this Belgian made sexy killing machine.
