Quick answer
Resupply 1.1 introduced weapon attachments: Muzzle Brakes (rifle recoil reduction), Compensators (pistol/rifle recoil + hip-fire spread), Laser Sights (Micro and Large variants for hip-fire spread reduction), and Shotgun Chokes (medium-range pellet tightening). Hold your firearm and press "Y" on keyboard (or D-Pad Down on controller) to open the attachment menu. Attachments spawn as field loot in gun shops, pawn shops, and weapon crates.

What to do in a live run
- 01Step 1
Equip the firearm in your active hands
Ensure the weapon you intend to modify is currently drawn, loaded and active in hands before attempting modification.
Official notesS1 - 02Step 2
Open the attachment wheel with "Y" or D-Pad Down
Press "Y" (keyboard) or D-Pad Down (controller). The interface displays available compatible attachments found in your inventory or ground proximity.
Official notesS1 - 03Step 3
Select the attachment to fit your combat engagement
Equip Laser Sights for tight indoor hip-firing, Muzzle Brakes for rapid rifle semi-auto follow-ups, Compensators for pistol control, or Chokes for medium-range shotgun buckshot concentration.
Field advice - 04Step 4
Weigh attachment inventory weight against ammo
Attachments consume precious inventory capacity. If you lack ammunition for the corresponding firearm type, prioritize medicine and extraction supplies over spare unmounted mods.
Field advice
Brief 01
The four confirmed attachment categories in Resupply 1.1
Official Resupply 1.1 notes define four distinct attachment groups: 1) Muzzle Brakes (available for small arms and rifles to significantly reduce vertical/horizontal climb); 2) Compensators (available for pistols and rifles, offering moderate recoil dampening paired with hip-fire spread reduction); 3) Laser Sights (split into Micro and Large variants, drastically narrowing hip-fire crosshairs without requiring ADS); and 4) Shotgun Chokes (constricting pellet cone for lethal medium-range buckshot density).
Brief 02
Scavenging strategy: Where to look for attachments
Attachments do not drop uniformly across all map areas. Scavenge high-tier weapon caches, security checkpoints, police armories, pawn shops, and gun store display racks in maps like Pottsville, Lewiston, and Power Plant. In Survival arenas, supply air drops frequently contain rare attachments to reinforce holdout positions.
Brief 03
Tactical tradeoffs: Hip-fire laser vs ADS discipline
While official design established that ADS grants the peak accuracy window for firearm shots, Resupply 1.1 laser sights provide a dedicated hip-fire fallback. In chaotic close-quarters horde encounters where ADS slows movement speed and restricts field of view, laser sights allow Responders to execute rapid defensive headshots on the run while preserving peripheral awareness.

Verification boundary: Unknown stat multipliers
In accordance with our independent verification policy, exact percentage values (e.g. precise recoil percentages or exact choke spread angles) have not been published by Torn Banner Studios. This wiki documents verified functionality and mechanic relationships rather than fabricating unverified numerical tables.
Before commitment
Run checklist
- Equip the firearm in hands before pressing the "Y" key.
- Check compatible slots: Muzzle, Rail or Barrel.
- Prioritize Laser Sights for close-range mobile protection.
- Do not hoard incompatible attachments over team supplies.
Decision support
Situation → action
| Situation | Action | Why |
|---|---|---|
| Clearing tight hallways and staircases | Equip Laser Sight (Micro or Large) | Maximizes hip-fire spread tightness without sacrificing movement speed or peripheral vision. |
| Holding long chokepoints with a rifle | Equip Muzzle Brake | Significantly dampens muzzle rise for rapid semi-automatic follow-up headshots. |
| Using a shotgun for street and courtyard defense | Equip Shotgun Choke | Concentrates pellet spread, extending one-shot kill consistency into medium ranges. |
| Carrying an attachment for a weapon you do not own | Drop or trade to teammates who hold the matching gun | Inventory space is needed for medical supplies and extracted Supplies haul. |
FAQ / practical answers
Questions players ask before the next run
How do you open the weapon attachments menu in NMRiH2?
While holding the firearm in your hands, press the "Y" key on keyboard or Down Arrow on the controller D-pad. If the weapon has compatible attachments in your inventory or on the ground, the equip wheel will appear.
Why does an attachment not appear or refuse to equip?
Attachments are slot- and weapon-specific. A shotgun choke cannot be fitted to a rifle, and specific pistol compensators require compatible barrel threads. If an option does not display, that firearm does not support that attachment model.
Where can I find weapon attachments on the map?
Look inside gun shops, security rooms, pawn shops, police departments, and military crates. In Survival mode, airdrop supply crates also frequently supply top-grade attachments.
What exact percentage does each attachment improve?
Torn Banner Studios has not published exact decimal or percentage stat changes for Resupply 1.1 attachments. Beware of unsourced tables on community wikis; official notes only confirm the qualitative effects.
Can weapon attachments be detached or swapped mid-match?
Yes. Press "Y" on keyboard or D-Pad Down while holding your weapon to open the modification wheel and swap attachments freely as you loot new parts.
