I have the best luck when using the Barrett with Stability and Variable Zoom. Although it doesn't actually increase the range rating of weapon it does make longer shots much easier and the reduced sway becomes a must have for those shots at max zoom. I also use claymores to cover my back and portable radar to keep a watch out for any Stalker Pro users who get past my claymore. My secondary is usually MP412 with a Tactical Knife. I use Blind Eye to keep air support off of me. Assassin is a must have for a sniping class in my opinion. My third perk is Marksman. It's great once you get it pro. I run the assault package on this class and set my killstreaks low. I have a UAV which is helpful no matter the situation. I have a care package because you can occasionally luck out and get something great and I also have an IMS because if your claymore gets taken out or gets a kill then it makes a great defensive weapon.

any advice? i have been using the RSASS with speed and thermal, but havent got that good luck.. i have tried changing the profiency, and its the same, i think im not good for being a sniper rifle user D:

acog is almost necessary on maps like dome. just sayin (my opinion)

-Stay at one spot, always stay hidden. Move around if enemies are spawning different -areas, depends the map.

-Always be behind cover.

-Always stay patient.

-True snipers don't use quick draw.

-Carry a portable radar and be aware of your surroundings.

-I use the 50. Cal Barret with two attachments, HBS and Extended Mag.

-My perk setup is scavanger, assasin, and marksmen all pro'd.

-Use Specalist if going for MOAB.

-Make sure to pick up someones weapon for a secondary sometime in case of CQC,

-If you kill a same guy twice in your area, he will keep going after you determined to kill you (even if he's dropping his KDR just to kill you)

-Someone will eventually try to counter snipe you, at that point keep moving left and right -when you see someone trying to snipe you. A moving target is always harder to hit.

-Don't try shooting in front of the person. Only at or slightly behind him.

-Torso and up should be one shot kills. If the target is moving spots you may try shooting him quick.

-If the enemy moves behind a wall try the shot anyways.

I have very limited experience with sniping (SMGs for me ), but these are some tips I picked up during my short reign of sniping and learning from enemy snipers' mistakes.

- Be patient! Don't expect to get a three killstreak the moment you start shooting

- Stealth is one of the most important traits of sniping. Use Assassin, Blind Eye, and possibly a silencer

- Claymores work both ways. They can either protect you or give your position away.

- Don't stay in the same spot for an entire life, unless you want a revenge-hungry enemy to shoot you in the back. Choose a spot, snipe one or two enemies, and move.

- Likewise, try to avoid going to the well-known sniping spots (e.g. the bunker on Outpost...)

- Finally, don't expect to be a 1337 MLG sniper right off the bat. Take your time and develop your skills.
