Weaknesses

It aims down sights slowly unless built for it, and its mobility is poor.

Perk and equipment notes

This is Gaming ProMax's first-choice general MP sniper class (cited). GPM lists alternatives: Overkill, Frag, Concussion, Portable Radar. 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. Dexerto (different build) agrees on Ninja, Battle Hardened and Sticky Grenade, but runs Quick Fix, Smoke Grenade and Portable Radar.

Source notes

Top-level velocity/adsMs/sprintToFireMs are Warzone base values (CODMunity weapon page and GGRanked Warzone page agree exactly). Class: sniper rifle (official patch notes, Dexerto, Games Atlas, GGRanked, mw4field) - matches our list; it is semi-automatic (no rechamber time; GGRanked, CODMunity). Games Atlas/Dexerto spell it 'Signal .50'. rpm 111 (GGRanked, CODMunity, Games Atlas, mw4field). Magazine 7 (GGRanked, CODMunity, Games Atlas, mw4field); reload 4967 (GGRanked, CODMunity). Head multiplier is CODMunity's stats-table value (table is labelled Warzone, but for this class it matches the GGRanked MP head/body ratio, not Warzone's). MP damage brackets GGRanked only (0-33 / 34-48 / 49-66 / 67+ m), no Season 1 changes to confirm. GGRanked MP body-part damage: head 234, neck 178, upper torso 132, lower torso 102, upper arm 104, lower arm 96, upper/lower leg 96 (vs MP health 100); CODMunity's MP build blurb also says it kills in one shot from the chest up. GGRanked Warzone body-part damage: head 305, neck/upper torso/upper arm 188, lower torso/lower arm/legs 141 (these do not line up with the 235 first-bracket value; shown as given). Not in CODMunity's MW4 TTK ranking. MP handling (GGRanked): velocity 600 m/s, ADS 590 ms, sprint-to-fire 283 ms. Warzone and DMZ damages agree (235 / 145 / 140) but bracket ends differ (14 / 49 vs 25 / 52 m); the DMZ page shows MP velocity/ADS (600 m/s, 590 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. Our one Warzone source contradicts itself for this gun (its range damage and body-part damage don't match), so we don't show a Warzone time to kill yet.
