M40A5

The M40A5 USMC Scout Sniper Rifle (known in-game as M40 or M40A5) is a 7.62mm sniper rifle. It is a long range weapon. The only other confirmed sniper rifle as of now is the TAC-50.

Pros
The M40 has a very high DPS. If you have good aim this gun is for you due to it being able to 2 shot most players though it is better to switch to another weapon after sniping once. This gun is also very accurate.

Cons
If you miss your shot, or fail the quickswitch anyone can rush you with a shotgun or SMG and you are done. This gun is also probably quite rare but less rare than the TAC-50.

Tips

Careful using this gun if you miss your d=shot you will be very vulnerable.
