About the M40A3
'Oh! I can't wait until I unlock the Barrett .50 Cal! All the other snipers suck.' That is a quote from a person I played with on Team Deathmatch a couple of months ago. At that time, I believed him. The Barrett .50 Cal has power and a high fire rate. I used the Barrett for a while, and then I decided to try the M40A3 just for the heck of it. I was astonished, and now its all I use. Don't be fooled by this sniper rifle's apparent mediocre damage-it has extreme accuracy, almost no recoil, and has a good feel. Besides, stopping power makes most M40A3 shots a one-shot kill. That is why the underrated M40A3 is the sniper rifle for me.
M40A3 PerksThe M40A3 is great with a variety of perks, so try which ones help you out the most. Here are my favorite:
M40A3 MapsJust as with any gun, the M40A3 can be played on any map-including Vacant. You just have to know how to use it and what perks to use. But here are some no-brainer M40A3 hot-spots. Shipment - Out of all the maps this map would probably be the best to use the M40A3 on. In this map there are lots of places that will require that you put rounds down range fast and accurate. This gun along with the perks above will help ensure that you get what you want out of that gun. Ambush: One of the best M40A3 snipe spots. I can get 20-30 kills with the M40 here on average. There are lots of secret hiding spots to snipe from too. Backlot: The M40A3 beasts here. Try sniping in the buildings, but beware of the rooftop sniping location. Bloc: The sniper's dream map. Be careful though-if you can see them, they can see you. Bog: Stay back with the M40A3 or go up to the risky hill. Either way, you can rack up some kills. Countdown: A great map for the M40A3-remember, elevation can help. Creek: Another sniper's dream map. Find a good camouflage spot in the grass or trees and snipe away. District: Stick to the long alleys-the marketplace won't treat you nice. Downpour: Here you have too options-stay back or go on top of the roof in the middle. Overgrown: At the beginning of the game, whoever can snipe fastest gets the kills. The M40A3, with its great accuracy, can get you 3-0 after ten seconds of playing. Pipeline: Go up on the roofs, and remember to set claymores up-and the enemy usually can come from different ways. Strike: The long streets make an M40A3 sniper happy. |
