Primary: HK417 "Recce" 14in for sub 1km (With AMS, HALO Suppressor and the isopod for bipod, bc why not :)) ) and M320 LRR for longer.
Clothing: Exile Woodland or Ghillie
Vest: Normally the OD Green Carrier Special
Backpack: 50l MOLLE
The main reason for the 417 is, with the MK362 ammo in it, it is a 1 shot sub 900m and only costs 800 pop tabs any other ammo and it is trash though.
Also, don't forget shitloads of duct tape.
Cost = Approximately 9k but that is mainly because I have like 4 grenades and defib, could easily get it to like 6k.
