The SR-3M SMG in Delta Force is an absolute powerhouse, boasting a great fire rate, solid damage, and versatility. In this guide, I’ll focus on boosting its range, taming its recoil, keeping the handling snappy, and improving stability for an all-around S-tier weapon. If our playstyles align, you’re going to love this setup as much as I do!
Best SR-3M Loadout
- Damage: 27 (effective range: 0–20m)
- Fire Rate: 747 RPM
- Time-to-Kill (TTK): ~240ms at close range, ~440ms at longer distances (56m+)
- Strengths: Exceptional TTK, manageable recoil, and high mobility.
- Limitations: Lower muzzle velocity makes it less effective beyond 60m.
The SR-3M shines in close to medium-range engagements. With the right attachments, you can optimize it for aggressive, fast-paced play while retaining precision and control.

Best Attachments
With all of that in mind, here are the attachments that you can use that will help with that, as well as some possible alternatives:
Barrel
- Attachment: SR-3M Extended Barrel
- Boosts effective range and control.
- Adds extra attachment slots for customization.
Muzzle
- Attachment: SMG Echo Suppressor
- Increases range and control.
- Provides sound suppression to keep you off the radar.
Foregrip
- Attachment: RK-04 Grip
- Reduces firing cam and visual recoil.
- Improves overall recoil stability.
Handguard (Rails)
- Attachment: Ranger Handguard
- Enhances recoil control for better accuracy.
- Alternative: DD Python Handguard for improved handling if you prioritize mobility.
Magazine
- Attachment: 45-Round Magazine
- Increases ammo capacity to sustain fire in intense fights.
- Slight trade-off in handling, but worth it for the SR-3M’s high fire rate.
Mag Mount
- Attachment: MagAssist
- Slightly boosts handling without any drawbacks.
Optic
- Attachment: Panoramic Red Dot
- Clean, unobstructed sight for quick target acquisition.
- Note: Optics are a personal choice—pick what feels right for you.
Rear Grip
- Attachment: AK Heavy Tower Grip + Stable Grip Base
- Adds stability and control without major trade-offs.
Stock
- Attachment: Elite Light Stock
- Improves handling, ADS movement speed, and control.
- Perfect for maintaining mobility in close-range combat.
Laser
- Attachment: Integrated Laser
- Cuts ADS time by 50ms for faster response in close-quarters gunfights.

Best Calibrations
To maximize performance, fine-tune these attachments:
Barrel
- Weight Limit: Default (to preserve ADS movement speed).
- Length: Maximize for increased muzzle velocity.
Foregrip
- Thickness: Minimize for improved ADS movement speed.
Rear Grip
- Weight Limit: Maximize for better control.
- Thickness: Default (to avoid hurting sprint-to-fire and stability stats).
Stock
- Weight Limit: Maximize for added control.
- Placement: Default (to maintain firing stability).
Optic
- Pupil Distance: Minimize to expand visibility within the optic window.

Wrapping Up
Testing this build in the firing range is a must! Recoil control is nearly effortless. Even without actively managing the spray, the SR-3M stays surprisingly stable. At 100m, landing shots is still easy, which is impressive for an SMG.
With these attachments and calibrations, here’s how the SR-3M performs:
- Control: Recoil is dramatically reduced, making precision easy.
- Handling: ADS speed hits a solid ~305ms with the laser, ideal for close combat.
- Mobility: High ADS movement speed keeps you nimble in firefights.
- Stability: Improved flinch resistance and firing stability ensure consistent performance.
This SR-3M loadout transforms the weapon into a top-tier SMG for close-quarters combat and mid-range engagements. The combination of control, mobility, and versatility makes it a perfect choice for aggressive players looking to dominate on the battlefield. Give it a try and let me know how it works for you!
