Compare it to the GOL. I miss easy shots, it could just be me but the accuracy is different.
It's probably just where the bullet drop is different. Where you are used to the GOL it messes you up with everything else. It happens to me when I switch to the GOL or M24.
Yes there is a full automatic sniper. It's the Vss. also instead of the spot you should put magnum ammo if you have it. its about a 4-5 shot kill with that on.
The VSS (second to last sniper) is pretty much full auto. A red dot on it is deadly.
And for side arms, the M1911 is the best for sure.
Then just use mortars and magnum ammo and you're ready to go.
Any one thats saying theres no full-auto sniper, hasnt used the sniper kit much, its the 2nd to last recon weapon you unlock, its call the VSS and it IS fully automatic.
