The WSP Swarm is an SMG in Modern Warfare 3 (2023) and Warzone.
In Modern Warfare 3, you can customise your extensive arsenal of weapons with attachments to modify their stats, courtesy of the gunsmith. With the right attachments, the WSP Swarm can be tailored to fit a variety of different play styles. Here's a set that's perfect for running and gunning:
The WSP Ruthless-L Barrel provides an increase in bullet velocity and range which helps in mid-range scenarios while the WSP Factory Stock enhances movement speed and aim walking speed which makes all the difference when strafing an opponent.
Next is the XTEN Phantom-5 Handstop to guarantee the fastest sprint-to-fire and aim-down sight speeds in addition to a slight reduction in vertical recoil. For further improvements to the WSP Swarm's accuracy, the WSP Hark Rubber Grip improves flinch resistance, allowing you to keep focused on the intended target.
We've only selected four attachments as we feel adding a fifth slows the fast reaction speeds created by this combination. If we do uncover a fifth, we'll be sure to update the guide.
