HRM-9 Best Loadout and Build

HRM-9 Attachment Setup

Muzzle Shadowstrike Suppressor S
Underbarrel Bruen Pivot Vertical Grip
Magazine 50 Round Drum
Rear Grip PCS-90 Assault Grip
Optic Slate Reflector

The HRM-9 has pretty good recoil control even on full auto, making it great for quick kills at short to medium ranges. To make it even more effective for pushing and CQB, we'll want to turn it into a suppressed variant, all while solving the issue of its low-capacity magazine.

Attach the Shadowstrike Suppressor S to make yourself undetectable by radar when firing. Then, attach the Bruen Pivot Vertical Grip and the PCS-90 Assault Grip to make recoil a non-issue entirely. Finally, slap on a 50 Round Drum to give yourself a bit of staying power during prolonged gunfights.

As for your Optic, it honestly varies by preference. However, we chose the fan-favorite Slate Reflector for its clear and unobstructed sight picture, perfect when doing fast-paced pushes and rotations around the map.

Secondary Renetti
Tactical Stun Grenade
Lethal Semtex
Field Equipment -
Vest Assassin Vest
Gloves Scavenger Gloves
Boots Covert Sneakers
Gear Ghost T/V Camo
Conversion Kit -

Since you'll want to constantly be pushing enemy spawns, this loadout and perk setup makes it so that you're effectively invisible on radar while allowing you to resupply behind enemy lines.

The Assassin Vest and Ghost T/V Camo make sure that you're invisible to all enemy recon killstreaks, while the Covert Sneakers are there to silence your footsteps. Equip the Scavenger Gloves to unlock the ability to resupply ammo from dead enemies.

To round it all off, equip the Renetti as your secondary since it's one of the better quickswap handguns due to its quick TTK. Even in its base version, this handgun can function as a primary weapon in a pinch.
