Overview

NoobFeed’s pick for stealth: flanking and quiet play, while still reliable at mid range. Oct 28 raised its head multiplier from 1.25 to 1.3 and buffed the Void Apex’s ranges. Season 1 raised its Medium Damage 2 (15 to 16) and minimum damage (13 to 14). Its blueprint can drop from Irradiated Containers in DMZ.

Strengths

The built-in suppressor frees the muzzle and barrel slots for other attachments.
Low recoil, good handling and a steady fire rate.

Weaknesses

Limited effective range; it struggles on wide maps with long sightlines.

The long barrel adds range to the suppressed gun, and dropping the stock restores mobility.

Perk and equipment notes

Only Gaming ProMax (cited, same build) lists perks. GPM/games.gg write 'Semtex'; MW4 multiplayer calls this lethal 'Sticky Grenade' (Dexerto's Sticky Grenade page slug contains 'semtex'), so it is recorded as Sticky Grenade. NoobFeed has no gun-specific perks. Dexerto's different build runs Quick Fix, Fast Hands, Blood Rush with Sticky Grenade and Flash Grenade.

Source notes

Top-level velocity/adsMs/sprintToFireMs are Warzone base values (CODMunity weapon page and GGRanked Warzone page agree exactly). rpm 800 and magazine 40 agree (GGRanked, CODMunity, mw4field); reload 2767 (GGRanked, CODMunity). Head multiplier 1.3 is the Season 1 patch value (1.25 -> 1.3, CODMunity patch history; CODMunity table 1.3). MP damage from GGRanked (0-10 / 11-19 / 20-29 / 30+ m); Medium Damage 2 = 16 and min 14 match Season 1 (15 -> 16, 13 -> 14; Dexerto and CODMunity). Season 1 arm/hand multipliers 0.95 -> 1. CODMunity TTK drops 9.8 / 17.8 / 26.7 m roughly track the MP brackets (build-based). DMZ damage values (35/30/25) differ from Warzone (34/31/26). MP handling (GGRanked): velocity 450 m/s, ADS 255 ms, sprint-to-fire 110 ms. Warzone profile is GGRanked only (low). DMZ profile is from GGRanked's DMZ page only; the page does not show which mode tab its stats block reflects, so treat as unconfirmed DMZ data. DMZ profile health is null: base health 150 is sourced (DMZ Codex) but armor per plate is not.
