OK, this is a very specific setup and playstyle you need to learn how to do well. Its quite similar to the M16A4, but with more recoil management.
SETUP:
Optic: M145
Barrel: Compensator
Underbarrel: Vertical Grip
Other: Green Laser
WHY THIS SETUP?
So, this doesn't help with the recoil that much, but its the best we've got. Hipfire is the main focus here. The compensator is for the M145's crosshairs, the grip is for hipfire and so is the laser.
HOW SHOULD YOU USE THIS SETUP?
OK, first, set your FAMAS to burst mode. That's two V-clicks. Now, use it on hipfire at close range and use a good long-range secondary like a DEAGLE 44 so you won't have to deal with enemies at long range. You need to use this on solo. However, its not a "get up and go" gun, either. Find cover. Hipfire from behind, and try to make sure all your shots hit. Use the good reload time to your advantage, too. If you're low on ammo and using this advice, reload behind cover too. You can also try whipping out your deagle if you need to, and always aim for the head.
PROS:
- Great ROF
- Great reload time for playstyle
CONS:
- Bad ADS recoil
- Bad long-range capability
- If you don't hit all your shots, you're dead. BT and on semi reccomended it you don't use the hipfire.
CONCLUSION:
This is a non-versatile setup with a very specific set of rules for its use. However, stick to these rules and you'll find yourself with (hopefully) some decent feeds.
