A brand-new trigger attachment has made the Lockwood 300 shotgun a one-shot kill in Warzone 2 – here’s the loadout you need to use:
| Attachment | Tuning | How to Unlock |
| Sakin DB107 (Muzzle) | +0.48 ↑ +0.18 → | Lockwood 300 Level 2 |
| Matuzek 812 Barrel (Barrel) | +0.30 ↑ +0.22 → | Lockwood 300 Level 14 |
| Point-G3P 04 (Laser) | -1.45 ↓ -1.65 → | Expedite 12 Level 11 |
| Heist Stock Mod (Stock) | +0.50 ↑ +0.24 → | Lockwood 300 Level 23 |
| Maelstrom Dual Trigger (Trigger Action) | N/A | 15 Point-Blank Operator Kills with the Lockwood 300 |
The key to this loadout is the Maelstrom Dual Trigger, as it allows you to fire two shots with one trigger pull. This attachment is what makes this particular Lockwood 300 essentially a one-shot kill up to around 10m when aiming down sights or around 5m when hip-firing.
Unfortunately, the Maelstrom Dual Trigger is banned in Warzone ranked. This means you cannot make a ‘one shot’ Lockwood 300 loadout in this game mode.
Alongside the Lockwood 300, we recommend using an assault rifle that is powerful at all ranges. This is because the Lockwood 300 is only effective up to 10m, and, even then, it takes a while to reload after every trigger pull.
These are the best ARs to use alongside the Lockwood 300:
How to Unlock Maelstrom Dual Trigger in Warzone 2 & MW2
To unlock the Maelstrom Dual Trigger attachment in Warzone 2 and MW2, you need to get 15 Point-Blank Operator Kills with the Lockwood 300.
The easiest way to do this is in MW2 Multiplayer, as the maps are much smaller and full of players. However, if you don’t have MW2, Plunder is also a good option for getting kills when next to enemy players.
Once you’ve unlocked this trigger attachment, you’ll be able to make the ‘one shot’ Lockwood 300 loadout in Warzone 2!
