Delta Force S7 MK4 Submachine Gun — Hazard Operations Loadouts & Build Codes (2025)

Introduction

In Delta Force Season 7, the MK4 is shaping up to be a piece of "hidden tech"—a secret weapon capable of melting enemies instantly via hip-fire, provided you master the right playstyle and loadout.

Officially positioned as a Tier 3 mid-to-close range SMG, the MK4 offers two distinct firing modes. While the full-auto mode is standard fare, it is functionally obsolete; the MP7 simply offers higher DPS and a cheaper base price for the same ammo type. However, the 3-Round Burst mode is where this weapon truly shines. With significantly superior stats and unique handling, its TTK is unexpectedly lethal. This guide compiles three verified MK4 loadouts from top-tier players, ranging from low-cost to high-end, all designed to help you dominate the battlefield regardless of your budget.

Delta Force Season 7: The Hip-Fire Advantage - Why MK4 Burst Mode?

Veterans who have used the MK4 know that its 3-round burst mechanism is incredibly fluid—it never "jams" and offers exceptional rhythm. In Havoc Warfare modes, it can even feel like a "OP" weapon.

Here is why the "Budget Hip-Fire" strat works so well: While most SMGs rely on hitting torso shots to kill quickly, they often suffer when hitting limbs. The MK4 solves this with high limb damage multipliers. Its damage tuning guarantees a kill within two bursts inside its effective range. Crucially, the burst fire mode incurs significantly less hip-fire spread penalty compared to full-auto, making it far more accurate from the hip than other SMGs with similar stats. Add in damage range drop-off stats that rival assault rifles, and the MK4’s burst performance is far better than the raw numbers suggest.

Below, we present three specific loadouts: the Budget Build, Standard Build, and Premium Build. As you move up the tiers, hip-fire accuracy improves drastically. The Premium Build, in particular, maximizes both hip-fire stats and ADS recoil control, making it a versatile "hybrid beast" capable of dominating in both close-quarters hip-fire and mid-range precision combat.

1. Delta Force S7 MK4 Budget Build

Loadouts Code：MK4 Submachine Gun-Operations-6IA0QF400RR8JACO27GDL

Key Parts:

Performance Highlights:

This budget build prioritizes Sustainable Firepower and Cost-Effectiveness. The centerpiece of this build is the 48-Round Mag, which provides a massive advantage in early-game engagements, allowing you to engage multiple targets without the risk of running dry. Paired with the ZFSG Tactical Grip and M7 Stable Rear Grip, this setup offers a solid baseline for recoil control, making the weapon controllable enough for close-quarters sprays without breaking the bank. It is the ideal "starter" loadout for farming bots and low-risk operations.

Value: 166,086 HAVOC (November 27th)

2. Delta Force S7 MK4 Standard Build

Loadouts Code：MK4 Submachine Gun-Operations-6IA0QJ000RR8JACO27GDL

Performance Highlights:

Compared to the Budget Build, the most significant upgrade here is the swap to the AR Heavy Tower Grip, made possible by installing the Balanced Grip Base. For calibration, we recommend maximizing the Weight Limit and minimizing the Thickness. While this slightly increases the cost, the payoff is a substantial boost in Recoil Control and Stability. In Operations mode, where mid-range skirmishes are frequent, this setup effectively transforms your MK4 into a stable "Short Assault Rifle." This loadout is versatile enough to handle the vast majority of battlefield scenarios.

Value: 245,894 HAVOC (November 27th)

3. Delta Force S7 MK4 Premium Build

Loadouts Code：MK4 Submachine Gun-Operations-6IA0QM800RR8JACO27GDL

Key Parts:

Performance Highlights:

The premium MK4 build transforms the weapon’s behavior, turning a standard SMG into a mid-range laser beam. By pairing the Sandstorm Vertical Compensator with the QR High-Performance Stock, we have eliminated vertical muzzle climb, allowing you to beam distant targets without needing aggressive recoil control. The EC Universal Front Hand Stop ensures the weapon remains snappy, balancing these heavy stability mods with excellent ergonomics so you never lose the initiative in close-quarters snap battles.

Value: 401,804 HAVOC (November 27th)

Conclusion

To wrap up, the MK4 in Season 7 tells a tale of two modes. You can safely ignore the Full-Auto mode—it simply doesn't compete with other SMGs in the current meta. However, the 3-Round Burst mode is a hidden gem with genuine competitive viability.

While it isn't perfect—we would love to see a future buff that reduces recoil slightly or adds a "hold-to-burst" mechanic for smoother handling—these are minor gripes. When you look at the price tag, the verdict is clear: for a weapon costing around 200,000, the return on investment is unbeatable. It delivers maxed-out performance for its price bracket, making it the ultimate budget beast for players who know how to control the burst.
