Patriot XMR in Modern Warfare 4: Top 6v6 Laser Setup and 50,000V Volt Apex Build
Modeled after the real-life modular PWS UXR rifle, the Patriot XMR stands out in Call of Duty: Modern Warfare 4 Multiplayer as one of the hardest-hitting full-auto assault rifles in the arsenal. Firing at a deliberate 645 RPM with a baseline 25-round magazine (and 100 rounds in reserve), it deals massive damage per shot across medium and long sightlines, but suffers out of the box from heavy vertical and horizontal recoil alongside sluggish handling. Here is how to unlock it quickly and which Gunsmith setups to run for a zero-recoil 6v6 beam or its signature 50,000V Patriot XMR Volt Apex attachment build.
How to Unlock the Patriot XMR and Its Level 72 Volt Apex Attachment
The base Patriot XMR unlocks as soon as you reach Player Level 27 in Multiplayer, seven levels before unlocking the rival Kastov 762 and its zero-recoil loadout at Level 34. Once added to your custom loadouts, the rifle features 72 weapon levels across nine attachment slots: Optic, Muzzle, Barrel, Underbarrel, Magazine, Rear Grip, Stock, Laser, and Ammunition.
Grinding all the way to the maximum Weapon Level 72 unlocks its signature modification: the Patriot XMR Volt Apex Attachment. This specialized underbarrel launcher fires a wide spread of non-lethal 50,000V electric darts up to 20 meters, overriding enemy fine motor control and paralyzing targets in place so you can finish them off with standard full-auto fire. To speed up the climb to Level 72, pop the Double Weapon XP tokens earned through the Modern Warfare 4 Season 1 Battle Pass and BlackCell bundle. Best of all, entering Weapon Prestige resets your weapon level to 1 for camo progression while keeping the Patriot XMR Volt Apex attachment permanently unlocked.
1. Best Zero-Recoil Patriot XMR Loadout for 6v6 Multiplayer
If you want a dependable primary weapon to lock down mid-range lanes and win long-distance duels without fighting heavy barrel kick, this standard meta configuration tames the rifle's recoil pattern while preserving snappy Aim Down Sight (ADS) speeds.
- Muzzle: EXP Undertow Gen. 2 (Unlocks at Weapon Level 25; suppresses radar gunfire while boosting bullet velocity, damage range, and accuracy)
- Optic: FJX 708 Pro (Unlocks at Weapon Level 19; provides a clean, unobstructed sight picture for tracking moving targets)
- Underbarrel: FSS Fireline Grip (Unlocks at Weapon Level 33; essential for stabilizing firing kick and horizontal bounce)
- Rear Grip: Schlager Attack-7 Grip (Unlocks at Weapon Level 28; locks down overall recoil control during sustained bursts)
- Laser: SA LAZ-500 (Unlocks at Weapon Level 12; speeds up ADS timing without projecting a visible laser beam to enemies)
Pairing the FSS Fireline Grip underbarrel with the Schlager Attack-7 Grip turns the Patriot XMR's wild kick into a tight, predictable grouping. Meanwhile, the SA LAZ-500 laser offsets the weight penalty of the EXP Undertow Gen. 2 suppressor without giving away your angle in tight corridors.
2. Best Patriot XMR Volt Apex Attachment Build (50,000V Stun Launcher)
Once you reach Weapon Level 72, equipping the Patriot XMR Volt Apex attachment changes how the rifle builds in the Gunsmith: the underbarrel electric dart launcher blocks barrel attachments and adds handling weight. To dominate close-to-mid engagements on objective modes, pair it with the Meiko 30CAL-SP muzzle and the Hanbit Mk.3 H70 stock to recover crucial ADS speed.
- Apex Attachment: Patriot XMR Volt (Unlocks at Weapon Level 72; fires a spread of 50,000V electric stun darts that paralyze opponents up to 20 meters away)
- Muzzle: Meiko 30CAL-SP (Provides sound suppression and firing stability when barrel attachments are blocked)
- Stock: Hanbit Mk.3 H70 (Significantly boosts ADS speed and handling for aggressive pushes)
- Laser: SA LAZ-500 (Stacks additional ADS speed without an exposed laser beam)
- Rear Grip: Schlager Attack-7 Grip (Keeps vertical and horizontal recoil in check during follow-up full-auto fire)
| Slot | Zero-Recoil Meta Build (6v6) | Volt Apex Build (50,000V Stun) |
|---|---|---|
| Muzzle | EXP Undertow Gen. 2 (Lv. 25) | Meiko 30CAL-SP |
| Optic / Apex | FJX 708 Pro (Lv. 19) | Patriot XMR Volt (Lv. 72) |
| Underbarrel / Stock | FSS Fireline Grip (Lv. 33) | Hanbit Mk.3 H70 |
| Rear Grip | Schlager Attack-7 Grip (Lv. 28) | Schlager Attack-7 Grip (Lv. 28) |
| Laser | SA LAZ-500 (Lv. 12) | SA LAZ-500 (Lv. 12) |
Best Perks and Equipment for the Patriot XMR
Because the Patriot XMR carries only 25 rounds per magazine and 100 reserve rounds by default, it burns through ammunition quickly on extended killstreaks. Your perk package and equipment should solve that ammo crunch while keeping you alive during objective pushes:
- Perk 1: Quick Fix to trigger immediate health regeneration after every elimination or objective capture, or Ghost to stay off enemy UAV sweeps while rotating.
- Perk 2: Scavenger to replenish ammunition from downed enemies, or Ninja to mute your footsteps when flanking.
- Perk 3: Birdseye to expand your minimap coverage and reveal enemy directional pings, or Battle Hardened to shrug off enemy flash and stun spam.
- Tactical & Lethal Equipment: A Flash Grenade (or Stun Grenade) to freeze opponents before swinging a corner, paired with a Sticky Bomb (Semtex) to flush defenders out of headglitches.
- Field Upgrade: Munitions Box (essential if you run Ninja instead of Scavenger) or Portable Radar to watch flank routes around Hardpoints.
My Take
The Patriot XMR tests your patience during its first twenty weapon levels because its raw kick and 25-round mag punish sloppy sprays. Once you unlock the FSS Fireline Grip, Schlager Attack-7 Grip, and SA LAZ-500 laser, however, its heavy per-shot damage at 645 RPM shreds opponents across mid-range lanes. Reaching Level 72 for the Patriot XMR Volt Apex attachment is also genuinely worth the grind: blasting a room camper with a 50,000V electric dart spread before cleaning them up with two rifle rounds makes breaking Hardpoint hills effortless.
