Umm, mainly Barrett/AK.
Barrett because I do usually alt. route on CW's.
AK because I have been using it for my entire "career", over 3 years now.
Other weapons I like are DE's, Spas and AUG. (Last ones handiness I actually discovered like in last 5 days or so)
DE's I use in realistic, alongside with Socom.
Ak/knife
Barrett/socom or LAW
others/any.
