really,save,next patch may be an94,good wep,i will get it to hear how others QQ at me XD

I'd say another pistol for bag 2. Doesn't have to be a Dagle, the 1911 is pimp if you are accurate.

I'd look for something with more range.

You have a SCAR-L which is well balanced, the AK is more for long range than the SCAR-L but is still effectve shorter, and the MP5 is the ultimate in-your-face up close prayers gun.

The only effective long range gun you have is the AWP. I'd look into a scoped AR or an auto-snipe.

I'd recommend an AUG. The SG is good but it is very annoying to listen to and the spray pattern is pretty wild. The AUG isn't as powerful but it is much more controlable, more accurate, faster, and quieter.

The XM is alright, but I find the scope hard to use. It throws me off more than anything else because it gives you tunnel vision. If you spray in scope, soon the bullets will be htting where you can't really see. It's for single-shot only.
Same with the G36 scope, though it is a little clearer to aim through.

The last gun I got was a Dragunov, and that thing is FUN! It's applications are a bit limited, but it's a 1 in the upper-chest kill and the ROF is nice so it can be as effective if not more effective than the AWP in the right hands.
However, the AWP has the limb-kill effect and the Dragunov can have poorer accuracy at long range.

I'd stay away from shotties. Although the 1 in the chest up close kill is nice, many users have difficulty with it and being a Winchester shooter myself I can attest to the frustration it can cause, especially with this game's joke of a hit-registration system.
Stick with the MP5 and aim high up close...
