According to my research, the best pointman weapon is AKS-74U Desmodus, the best rifleman weapon is the G36 Alligator.
I already have the desmodus and I am getting a lot of AP soon to get other things. So lets get to the point...

I know that the best snipers are M40A5, FR-F2 (mid-range) and Mosin Nagant (CQC sniper). I am not sure whether to waste my AP on mega capsules and try to get a permanent FR-F2 or just get a Mosin with red tickets from the capsule shop.
Any advice is appreciated.
