Lord..some of these responses lol.
So you're on a 110k budget?
- M107 - Great sniper and PK gun. I think it 110k exact I forgot. 12 dmg perfect, decent fire rate but the drawback is 10 clip and no spread. The freeze is decent as well.
- Default Rifle - All around great gun. Cheaper than M4 by 5k and has kinda better stats. Also comes with player made custom skins so that's cool.
- Tec9- 45k gun. Fast RoF, high spread, low freeze and 24 clip makes this gun really good. Only drawback is that it's 8 damage perfect but at the same time, the gun can still melt. When I played, I would still use it a lot even when I had BAR, PBP, etc..
- PDW - 75k. The PDW is a unique gun in which it's hit timer is glitched and broken. This means each bullet that hits will count as damage as rather then being a delay between each bullet. This gun packs a punch too since it has a fast ROF and low to medium spread. It does 9 damage perfect and it's a great PK gun. Drawbacks include 13 clip and slightly high freeze.
Hope this helps a bit.
