Assault Rifles - M-76 Revenant
Submachine Guns - M-9 Tempest
Heavy Pistols - M-6 Carnifex
Total Weight: Power Recharge Speed +58%
Soldiers are designed to be an expert in barrages of gunfire. High-level soldiers can use three different kind of special ammo types, which are Incendiary, Disruptor, and Cryo. A soldier type also has the unique ability to use Adrenaline Rush, which allow them to focus on targets with lethal accuracy causing heavy damage against the enemies. That's why your best picks are the M-76 Revenant, M-9 Tempest, and M-6 Carnifex.
The M-76 Revenant has a high fire rate and does a good amount of damage, however, the accuracy is really low, but with the Adrenaline Rush ability, it will increase your accuracy greatly, especially if you add the scope mod to it.
The M-9 Tempest is lightweight and has a whole lot of bullets to empty out quickly. The accuracy is better then the M-76 Revenant, but only use this sub machine gun for medium/close range combat.
The M-6 Carnifex is highly accurate and a lethal pistol to use. Although the fire rate is slow, a couple of hits from this gun should make short work of any bad guy.
Sniper Rifles: M-92 Mantis
Heavy Pistols: M-5 Phalanx
Total Weight: Power Recharge Speed: +122%
Infiltrators are tech and combat specialists with the unique ability to cloak themselves from visual and technological detection. Infiltrators are best with a sniper rifle. They have the ability to slow down time momentary to pick off their target.
The M-92 Mantis is a very powerful sniper rifle, able to kill an enemy in one shot. The accuracy is very high and doesn't weigh as much as the Black Widow. However, the only problem is the slow fire rate and the low amount of bullets you can hold. Beside that, it's still the best sniper rifle for an Infiltrator who wants to carry light, but still do heavy damage.
The M-5 Phalanx is a great gunwhen combined with the M-92 Mantis. Its fire rate is medium, has a good amount of damage, and holds a decent amount of bullets, creating a deadly close combat attack for enemies. When you run out of bullets for the M-92 Mantis, you can cloak yourselves and take the battle up close.
Shotguns: Graal Spike Thrower
Heavy Pistols: Scorpion
Total Weight: Power Recharge Speed +16%
Vanguards are the best in close combat. Charging into the battlefield quickly at enemies can destroy them instantly with biotic abilities. The biotic charge that strikes the opponent with incredible force stuns or knocks them down, leaving them opening for a blast of bullets.
The Graal Spike Thrower is one deadly shotgun and pretty light to carry. Of course with shotguns, they have a slow fire rate and low amount of bullets, but the Graal Spike Thrower has a little edge when it comes to accuracy. When you have one shot to take down the enemy you want to make sure the shot hits him.
The Scorpion is the perfect companion when you need accuracy by your side. What makes the Scorpion different from other heavy pistols are the explosive bullets. That's right! These bullets stick to your enemies and blow up causing great damage to their body. Although, the bullets are slower when fired, this pistol works great against those automatic turrets.
Assault Rifles: M-15 Vindicator
Heavy Pistols: Scorpion
Total Weight: Power Recharge Speed +138%
Sentinels have an advanced shield that makes them tough to destroy. I wouldn't recommend just rushing the enemies just because you have a tough shield though pushing forward is a great way to use the armor system. You can take a couple of shots, but a turret or mech can easily get rid of that shield in an instant.
The M-15 Vindicator fires in three-round bursts creating the opportunity to do a good amount of damage while having great abilities accessible. It's great at any range and definitely is light enough for Sentinel types to use their biotic abilities quickly.
Heavy Pistols: M-6 Carnifex
Total Weight: Power Recharge Speed +200%
Adepts are all about biotics. Capable of killing enemies with raw biotic power, this type doesn't need advanced weapon combat. They can defeat enemies without firing a single shot. They have the ability to spawn a singularity, damaging enemies and pulling them into the air for your team members to finish them out.
The M-6 Carnifex provides Adept characters with the opportunity to unleash heavy damage and still have great accuracy. Most of the time you won't be using guns to defeat your opponent, but when you do, you can count on the M-6 Carnifex to do the job.
Sub machines: M-12 Locust
Total Weight: Power Recharge Speed +141%
Engineers are the most effective class at disabling the defenses of enemies or incapacitating them, especially via their unique ability to create combat drones to force enemies out of cover.
The M-12 Locust is perfect for Engineers as it has a very high level of accuracy and capacity providing a barrage of bullets to hit defenseless enemies. As combat drones force them out of cover that's your chance to spring up and unload your clip.
The Scorpion is even more effective for Engineers that lower enemy defenses before firing. Again, although, the bullets are slow, the combat drone will distract the enemy opening up an opportunity to fire.
