When the Bruen MK9 is converted into an assault rifle this is easily one of the best guns in the game with an incredibly high time to kill With some of the highest damage output in the entirety of Warzone!
Whilst this gun is an LMG, converting it to an Assault Rifle with the correct attachments works even better than using it as an LMG, so here are the exact attachments you need to do that for the Bruen MK9 to dominate enemies in Warzone Season 3!

What Secondary Gun to use with the Bruen MK9 in Warzone

The Bruen MK9 is arguable the best gun to use at range in the current meta of Call of Duty Modern Warfare 3 and Warzone season 3, but it does struggle in the close-range gunfights, which are very prevalent in game modes such as Resurgence – especially on Rebirth Island!
We recommend taking an SMG as your secondary weapon so that when you’re in a building or right next to an enemy you can easily burst them down, and get back to shooting your enemies at long range with the Bruen MK9!
Here are the best SMG guns we recommend you take as your secondary weapon to accompany the Bruen MK9 and make the perfect loadout for any range gunfight:
- RAM-9
- HRM-9
- Striker
- AMR-9
- WSP-9
- Striker 9
These SMG guns are all insane because they have incredible manoeuvrability. This is the meta for SMGs at the moment, with there being a heavy focus on making sure the enemy can’t land all of their bullets as headshots rather than stationary gunfights.
The AMR-9 recently received a new Conversion Kit that allows it to become the most powerful burst-fire gun in the game, whilst the Striker, WSP-9, and Striker-9 all received buffs to their damage output and time-to-kill, so you have a load of meta SMGs to try out!

What Tactical and Lethal to use with the Bruen MK9 in Warzone

For tacticals in Lethals these are usually completely up to you, but there are a few that are better than others in our opinion, and you can decide based on your playstyle.
Tactical:
- Smoke Grenade
- Stim
Lethal:

- Semtex
- Thermite
- Throwing Knife
Choosing between Smoke Grenades and Stims is completely preferential, as Smoke Grenades provides with a lot of safety, but Stims are a lot better in the close quarters of a Resurgence map – specifically on Rebirth Island right now.
When deciding on a Lethal to take, both a Semtex and a Throwing Knife are the most popular options right now as they allow players to instantly finish off down enemies without having to shoot them and potentially get caught thirsting for a kill.
Thermites have always been a good Lethal to choose as they deal a large amount of damage in a large area so they are great for throwing into a room and preventing enemies from pushing or leaving.
