The DSR-IAR in Battlefield 6 is a very versatile LMG that combines firepower and mobility, making it a great choice for Support players. Whether you want to run and gun across the battlefield on an aggressive build or have a heavy, bipod-shot build while attempting to hold down key positions, the DSR can accommodate your play style quite easily. This guide will discuss the best attachments and builds for optimal effectiveness.
Playstyle Options for DRS-IAR

Stationary Heavy LMG Build
This variant fully embraces the LMG portion of the DSR, making it the best for defensive positions. If you mount the gun with a bipod, you will gain the best accuracy and sustained fire on targets at longer distances.
For the Heavy LMG DSR-IAR, the Compensated Brake greatly reduces recoil but does not provide minimap stealth. The 20″ SDM-R Heavy Extended barrel increases controllability at long distances while slightly decreasing mobility, and the bipod underbarrel wreaks havoc using sustained fire.
The 5mw Green laser tightens hipfire, the 50 Round magazine gives extra ammo at the cost of speed, and Standard ammo keeps things reliable and budget-friendly.
This one’s best for players who like holding points, suppressing enemies, or engaging multiple targets at mid-to-long range.
Run-and-Gun Assault Build
If you prefer your DSR to be akin to a snappy, reactive AR, this configuration is perfect for you. It prioritizes mobility and recoil control so you can remain in action without being encumbered.
For the Assault-style DSR-IAR, the Double-Port Brake suppresses recoil for more consistent firing, but does not hide you from the map. The 16.5″ LSW Heavy barrel stabilizes at longer ranges without reducing bullet velocity, and the Low Profile Stubby underbarrel improves recoil control and aims down sights faster at the loss of some moving accuracy.
The 5mw Green laser sharpens hipfire precision, and the 30 Fast magazine keeps reloads quick to maintain momentum. Rounding out the setup, Standard ammo is reliable and cost-effective.
This is best for players who like to stay mobile, push objectives, or complete Support challenges without being stuck in one spot.
