The weapons in Rainbow Six: Siege are incredibly diverse, especially among the weapons that the attacker operators use since these characters need to be versatile to defeat the defenders. Guns of all types can be equipped, including SMGs, assault rifles, and even light machine guns.

Every player should know about the different guns for the attacker operators, which ones are worth using, and which guns you should avoid. The best weapons in Rainbow Six: Siege often have a high rate of fire, a quick reload time, and a large ammo magazine.
Updated June 6 2023, by Jack Webb: Rainbow Six Siege is an ever-evolving game with so many characters to play and weapons to equip. As more patches, reworks, and other content is added, these weapons change almost as much as the gadgets do. We have added more weapons to this list you should consider using when you play as an attacker.
24 6P41 LMG
Finka and Fuse both have exclusive access to the 6P41, which is quite the weapon if you like LMGs. This gun has a very high ammo capacity, which is to be expected with an LMG. However, it also deals much more damage per bullet than most guns.
The reload time is quite slow for the 6P41 LMG, though, which is a disadvantage that you shouldn't ignore, but it's not too big of a problem since its magazine is so large to begin with. High damage per shot and a large magazine are enough to push the 6P41 over the edge as a very powerful LMG for both Finka and Fuse.
23 417 Rifle
If you like rifles, then you'll quickly fall in love with the 417. The 417 Rifle is available for Sens, Twitch, and Lion, giving it a wide enough availability to make it useful for many players across this FPS. Although this weapon isn't particularly useful for close-range encounters, it excels at range, which is often more important.
The 417 has low recoil, making it easy to aim, as well as dealing a significant amount of damage in each shot, so you can fire single bullets and still down enemies. If you're playing as any of the previously mentioned operators, then it's worth giving the 417 Rifle a try; you won't be disappointed.
22 CSRX 300 Rifle
Unlike most other weapons in Rainbow Six Siege, the CSRX 300 Rifle is only available to Kali, which makes it a fun, exclusive feature for playing as this operator. Unfortunately, there aren't any attachments for the CSRX 300, but it does come with a scope by default. Not only is there a scope, but it has multiple zoom-in modes, including 5x and 12x.

The downsides to the CSRX 300 are clear, you'll lose movement speed, and there isn't much extra ammo to work with should you shoot a lot of bullets. However, the CSRX 300 is still very strong since it can one-shot most operators who aren't wearing any extra armour, should your shot hit.
21 BOSG.12.2 Shotgun
The BOSG.12.2 is an incredibly powerful shotgun for Vigil and Dokkaebi. It functions differently than most shotguns, firing a single bullet instead of a spread. As such, it has a longer range, so it can defeat enemies from much further away while keeping its high damage.
In addition to the BOSG.12.2's longer range, it also has a quick fire rate and a large ammo reserve for you to use. The only problem you'll run into with this shotgun is its small magazine. You can amend that by aiming your shots with precision and finding cover to reload when necessary, making this a minor disadvantage.
20 PARA 308 Rifle
Capitao is the exclusive user of the PARA 308 Rifle. Despite its lack of availability for operators overall, it's still an exceptional weapon you should know about. The Para 308 Rifle has a slow fire rate, but its many advantages outweigh this single downside.
For starters, PARA 308 has many attachments available for use, allowing you to customize it your own way. Additionally, it has high damage per shot and minimum recoil, making it ideal if you're new to Rainbow Six Siege. Overall, you should learn how to handle the PARA 308 Rifle if you enjoy playing as Capitao.
19 G36C Assault Rifle
Iana and Ash are the two operators that can equip the G36C, and it suits them well because of its high-precision nature. The G36C isn't the best gun for high damage output, but it has a decent fire rate that makes up for its mediocre base damage.
RELATED: Rainbow Six Siege: The Best Secondary Gadgets
Fortunately, the G36C has a major advantage because of its low recoil. If you prefer precision and don't want to deal with the effects of recoil, then the G36C works perfectly. For those run-and-gun Ash players, this gun is one devastating weapon.
18
17 V308 Assault Rifle
Lion has a lot of great guns at his disposal, and the V308 definitely doesn't fall short. The V308 has high damage per shot but also a large magazine, so you don't need to reload often.
Even when you do need to reload, it comes with a quick reload speed, creating the ultimate combination. However, patience is key with the V308 since it has a slow fire rate. This gun technically isn't an LMG, but when you have over 50 rounds in a magazine, there is always a reflex to want to relead even after shooting two bullets. Try to remember you have plenty of rounds to spare.
16 L85A2 Assault Rifle
Recruit, Sledge, and Thatcher all have access to the L85A2 assault rifle, so you can use it with a wide range of characters. However, the L85A2 is known for more than its broad appeal because the gun itself has lots of reasons to equip it. It is an excellent all-rounder AR, and easily the best weapon for Sledge over his shotgun.
The L85A2 is mostly known for its high base damage, but it also outputs low amounts of vertical recoil. You'll have to deal with a slow fire rate and high horizontal recoil, but it's worth it if its advantages work well with your play style.

14 F2 Assault Rifle
The F2 assault rifle is Twitch's signature weapon, and it's considered one of the strongest rifles because of its high fire rate. The F2 is particularly effective at medium-range, which works well for Twitch since she is a medium-range operator.

You can equip the F2 with a ton of different attachments. Adding an ACOG sight is the most important thing you can attach to this rifle, just make sure you're keeping an eye on the recoil. When it comes to Twitch, there's no better choice over this or her Marksman Rifle, it depends on your playstyle.
13 MP7
Zero is the only attacker that can equip the MP7; however, Bandit can also use it, although he is a defending operator. The M7 is renowned for its high damage during close-range encounters; however, it can also be used effectively at medium-range with the right attachments.
The main downside of the MP7 is that it lacks grips. This problem is negated by its quick fire and damage rate, which are unmatched by Zero in all of his other guns.
12 M4 Assault Rifle
Maverick is the only operator that can use the M4; though it's exclusive to this operator, it's still an incredibly popular gun among Siege aficionados. The main reason for this is its potential for customization with attachments and its incredibly high damage output.
There is quite a bit of recoil on the M4 assault rifle. However, it's still better than any other weapon that Maverick has in his arsenal. The M4 is a great choice if you want a versatile weapon.
11 M762 Assault Rifle
The M7 AR is used by Zofia, and it's the best option for her by far. While it's not recommended to use, there is a burst function that can be good for you depending on how that meshes with you. Generally speaking, you'll want to keep the firing mode in full automatic.

It has high damage per shot and a decent rate of fire. It can run a 2x ACOG and it shines with a Vertical Grip. Putting a silencer on this gun doesn't hinder it too much, but this is a preference thing. Generally speaking, this gun requires no additions other than a scope and a muzzle to make it shine.
10 T-95 LSW LMG
When you're trying to bust into a room full of people who have been blinded by Ying's flash gadget, you need as many bullets as possible to get the most of out the opportunity.
The T-95 LMG is accurate, powerful, and has plenty of rounds to spare in a magazine. The power of this gun can down one-armour defenders in very few shots, and the gun doesn't have much recoil at all. It's not as fast as other LMGs, but this gun is unique to Ying and it's easily her most powerful.
9 AK-12 Rifle
Ace and Fuze both have the AK-12 rifle available in their loadouts, and it's the best weapon to use for both of them, mostly because of its high rate of fire.
However, you should only attempt to use this gun if you already have a lot of experience in Rainbow Six: Siege since it is somewhat difficult to handle because of its high recoil. Even with its large amount of recoil, the AK-12 stacks up as one of the best attacker weapons in Rainbow Six: Siege and one of the best weapons in the game in general.
8 C7E Rifle
Jackal has a few different guns to choose from in his loadout, but the best weapon to equip for this operator is, hands down, the C7E rifle. This rifle has more advantages than it does disadvantages, with a high rate of fire, a quick reload speed, and a surprisingly low amount of recoil.
Related: Rainbow Six Siege - The Ultimate Guide To Playing Smoke
The main disadvantage of the C7E rifle is its small magazine; however, this is mitigated by the fact that the reload time is very short. If you are playing Jackal, you should learn how to use the C7E assault rifle since it's such a great asset to use against the enemy team.
7 AK-74M AR
While this gun is fairly bog standard, especially compared to Nomad's ARX, the magazine capacity of this AK is what puts it ahead. It has a slower rate of fire, but the damage is considerable. We all want to make instant headshots in Siege, but sometimes we need more than one bullet, and in most cases, we'll need more than 30.
With over 40 rounds in a magazine, the AK-74 is a great option for Nomad, who wants to be in mid-range fights, ideally taking out someone who has just tripped over one of her Airjab traps. We'd always recommend Attackers taking 2x ACOG scopes when possible since it gives you a considerable edge over the Defenders who don't have long-range scopes.
6 G8A1 LMG
IQ and Amaru are the only characters that can use this LMG, and based on their play styles, this gun fits them perfectly in most situations. It's surprising how powerful this LMG is as it has a high ammo magazine, fast reload time, and higher-than-average damage output.
It takes longer than usual for the G8A1 to aim down sights; however, this is a small disadvantage compared to some other attacker weapons in Rainbow Six: Siege. This is the perfect weapon if you don't like to reload very often and don't want to worry about running out of ammo during combat.
5 OTS-03
There aren't many marksman rifles in Rainbow Six: Siege, which is why the OTS-03 is one of the best attacker weapons in the game. This weapon is exclusive to Glaz and has a sight that allows you to detect enemy movement using thermal tracking.
Related: The Best Games With Friendly Fire
The OTS-03 deals a lot of damage in a single shot; however, it has a small ammo magazine, so you need to be careful about hitting your shots and close-range combat. Glaz is a great operator if you learn how to use his arsenal correctly, and this weapon is one of the main reasons why he is so powerful.
