The HRM-9 sits in the Good tier for Warzone SMGs, and its 272ms close-range TTK at 882 RPM makes it a strong pick for players who push fights aggressively. Here's the build that gets the most out of it.

Best HRM-9 Build
| Slot | Attachment | |---|---| | Muzzle | Bruen Pendulum | | Barrel | Thorn-90 Barrel | | Underbarrel | Jak Slash | | Magazine | 50 Round Drum | | Stock | Folding Stock |
This build prioritizes recoil control and magazine capacity — the two areas where the base HRM-9 needs the most help. The Bruen Pendulum and Jak Slash work together to pull down the gun's 42.75 units of vertical recoil, while the Thorn-90 Barrel tightens overall bullet grouping. The Folding Stock rounds out the handling, and the 50 Round Drum bumps capacity from the stock 30 rounds up to 50 — critical for squad fights where 30 rounds can leave you dry mid-gunfight.
HRM-9 Damage Profile
The HRM-9 runs a three-range damage model:
| Range | Head | Chest | Stomach | Legs | |---|---|---|---|---| | 0–10.6m | 39 | 34 | 28 | 28 | | 10.6–17.7m | 32 | 28 | 23 | 23 | | 17.7m+ | 24 | 21 | 17 | 17 |
Inside 10.6 meters, the chest damage of 34 per hit translates directly to that 272ms TTK — highly competitive among SMGs. Beyond that first breakpoint the damage drops to 28 chest, pushing the TTK out to 476ms, which is considerably slower. This is a gun that rewards you for staying in its effective range and punishes overextension hard.
The third damage range (17.7m+) drops to just 21 chest damage, meaning you need significantly more bullets to kill. Do not take these fights voluntarily.
Key Stats at a Glance
- Fire Rate: 882.4 RPM
- ADS Time: 208ms
- Bullet Velocity: 460 m/s
- Close TTK: 272ms
- Long TTK: 476ms
- Base Magazine: 30 rounds (50 with Drum)
- Vertical Recoil: 42.75 (stock)
The 208ms ADS is fast for an SMG build running a muzzle and barrel, and the 460 m/s bullet velocity is adequate for the ranges you should be fighting at. You won't notice velocity issues inside buildings or during close rotations.
Strengths and Weaknesses
Strengths:
- High fire rate (882 RPM) delivers fast TTK up close
- 272ms close-range TTK competes well within the SMG class
- Snappy 208ms ADS keeps the gun responsive
Weaknesses:
- 42.75 vertical recoil is steep — the attachment slots lean heavily into controlling it, which limits flexibility
- Damage falls off sharply after 10.6m, making the gun range-dependent
- The 50 Round Drum is close to mandatory for quads, costing a slot
How It Compares
If you're weighing the HRM-9 against other SMGs, the AMR9 is its closest competitor in the Good tier. The AMR9 tends to offer easier recoil control at the expense of raw TTK speed. The C9 and Carbon 57, both sitting in the Very Good tier, are worth considering if you want slightly more versatility across ranges.

How to Play the HRM-9
This is a close-range aggressive weapon. The data makes the playstyle obvious: you have a 272ms TTK inside 10.6 meters and a 476ms TTK beyond it. That's a 75% increase in time-to-kill the moment you step outside the first damage range.
- Push buildings and tight spaces. The HRM-9 thrives in CQB where its fire rate and TTK dominate.
- Pair with a long-range primary. An AR or sniper to cover the gaps this gun can't fill.
- Pre-ADS around corners. The 208ms ADS is fast, but pre-aiming tight angles makes the TTK advantage even harder to beat.
- Don't challenge at range. 21 chest damage at 17.7m+ means you'll lose to almost any AR or even slower SMGs that hold their damage better.
