Ok, so this might be weird. A guide on a secondary weapon? WTF?
Well, it may seem weird at first, but in fact the M93 is FREAKING OVERPOWERED! THIS IS THE NEW AKIMBO MODEL 1887S!
Ok, odd introduction aside.
What is the M93 Raffica?
The M93 Raffica is a secondary machine pistol, unlocked at level 38. It's a variant of the M9 pistol, and looks similar.
It features a 20 round magazine which can be upgraded to 30 with Ext. Mags, and has several attachments:
Red Dot Sight at 10 kills
Silencer at 25 kills
FMJ at 50 kills
Akimbo at 75 kills
Holographic Sight at 100 kills
Extended Mags at 150 kills
What makes the Raffica so good?
There are several answers to this, all facts.
It has a 40-30 damage rating, making it the best for the machine pistols.
It sports a 3 round burst, like the M16A4.
It has the best accuracy out of all the machine pistols, and is on par with the Assault Rifles.
It has the second best draw speed of the Machine Pistols, the best being the G18.
It can be used in Last Stand.
Pay attention to the last note as it is very important.
A good class for the M93
The M93 Raffica is good enough to be used as a primary, but it can also be easily fitted into your normal class.
Your choice of SMG, Assault Rifle, Sniper Rifle, LMG, or Riot Shield.
Akimbo Model 1887s. LOL!
Jk they suck now, go Akimbo Rangers [/sarcasm]
Your choice of the Frag Grenade, Semtex, Tactical Insertion, Blast Shield, Throwing Knife, Claymore or C4.
Your choice of... Ok wtf you know them all.
It's really up to the class.
Stopping Power, maybe Cold-Blooded if you're going stealth.
Last Stand. This makes you have a freaking Mini-M16 when you are downed.
Whatever you want.
Attachments and their uses
Disclaimer: I am not going to rate the attachments as they all have their uses.
Red Dot Sight
Great if you hate the pistol iron sights. Note that there is less zoom than the RDS on primary weapons.
Good for stealth, or just general purpose as this gun is a 3 shot kill at far range with SP.
Many people disregard this attachment on the M93 because of the 3 round burst, but Akimbo has it's uses, such as complete ownage at close range.
Good if you like wall penetration. DOES NOT INCREASE DAMAGE!
See Red Dot Sight
This attachment makes the Raffica=M16A4. Lol.
20 round magazine turns to 30.
Strategies with the M93 Raffica
There are 3 approaches to using this gun.
Use it as a primary. Stick RDS/Holographic and Ext. Mags (Bling) and pretend it's a M16. Or you can just use it all the time.
If you are taking this approach, remember that this pistol is 3 round burst, not full auto. Also, if you get downed into Last Stand the number of bullets in the magazine does not replenish, so be careful.
Use it for room clearing/CQB. This gun isn't as suited to CQB as the other machine pistols, but it is still effective, especially in a larger room clearing situation. Remember it's a 3 round burst, and try not to hip-fire.
Use it for kinda-quick swapping and Last Stand. This is the approach most people take. When their primary runs out of ammo in it's magazine, you can whip out this machine pistol at almost the speed of a normal pistol. It also has the benefits of COMPLETE PWNAGE. In Last Stand, just aim and shoot. Remember about the 3 round burst, and have quick reflexes. Also, if you have the Pro version, kill yourself with a grenade after/if you kill your attacker.
Comments/Feedback welcome. I'll add more later if needed, kinda tired now.
