I will admit I'm no genius, but here are some tips that I find
useful when engaging in long range combat.
First off, we will start with the Recon Kit and different
Your primary weapon should reflect the map you are palying on, on
maps that are smaller (i.e. Grand Bazaar) the semi-automatic rifles
should be your choice. Wheras on longer range maps (i.e. Operation
Firestorm) a bolt action rifle should be used.
Next, the specifc rifle.
From what I have seen, the two best general useage bolt action
rifles are the L96A1 and the M40A5. The L96 is better for lower
profile engagements (as it can accept the flash suppressor) and the
M40 is good since it has the fastest bolt cycle. At long range, the
M98B is the superior weapon.
