I can help you learn how to become a better sniper in general. Although I haven't been sniping recently because Quarantine Regen has gotten all my attention lately due me trying to level and waste all of my EXP passes. I'm "rusty" at sniping, but i'll see what I can do to help.
Send me a PM and i'll reply back with my IGN. I'm on frequently, but if you needed to contact me otherwise, just send me a VM here.
