It's hands down the best gun in the game to use...only when there's minimum lag, or you'll burn through ammo in just a few kills

I love the gun, but being single fire how effective you are with it depends hugely on the connection.  You can probably say that about all the guns but I find the single fire makes it stand out.  Good way to start a session though, gives you a good idea of how good or bad you are lagging!

I can't use the iron sights on the gun, I need the red dot sight. I prefer extended mags + red dot. I used to use assault package with the MK14, with assassin as my 2nd tier perk. Since using specialist I've started using quickdraw instead and unlocking assassin in specialist. If you use sitrep pro as your third tier perk, you're able to get the jump on people up close, aswel as being able to dominate at long distance.
