In the Call of Duty: Modern Warfare 2 beta, all M4 attachments were confirmed ...

Call of Duty: Moden Warfare II improved the Gunsmith system, and players everywhere are getting their hands on it during the beta. The classic M4 platform is a fully-automatic assault rifle that you can upgrade to level 20 during the beta period. Additional attachments will be locked until the game officially releases on October 28.

In Call of Duty: Modern Warfare II, M4 attachments are included.

The Modern Warfare II beta allows players to only use a small number of possible attachments, while the more famous ones remain hidden for the time being. There are dozens of additional options marked Classified that we do not even know the names of.


Muzzle attachments either reduce the weapon's effectiveness or make it simpler to control, while reducing aiming stability, lowering sight speed, and/or damage range.

  • Echoline GS-X Suppressor
  • Bruen SPearhead Suppressor
  • Domodo Heavy Comp
  • Forge-Tac Castle Comp
  • C400 Door Knocker


With most of them, barrel attachments aid with aiming stability and recoil reduction, while others enhance damage range and bullet velocity. Youll be sacrificing hipfire precision and movement speed.

  • Tempus Trench Pro
  • Tempus Hightower 20 Barrel
  • 11.5 T-H4 Barrel
  • 14 Carbine Shroud Barrel
  • 7.5 Tempus Firebrand Barrel
  • 419mm EXF Barrel
  • LX-97 Torque Barrel

Laser technology is becoming more prevalent.

Laser attachments are all about hipfire accuracy and have few drawbacks; the greatest is the fact that the laser is visible in the game.

  • 4MW Laser Box
  • Corvus PEQ Beam-5


Sniper scopes also have a visible glint that enemies can see.

  • SZ Reflex
  • SZ Mini
  • Cronen Mini Red Dot
  • SZ Lonewolf Optic
  • Schlager 4X
  • Forge-Tac Delta 4
  • Hybrid Firepoint
  • Thermo-Optic X9
  • HMW-20
  • DS Warme Zielfernrohr

Stocks are a popular stock.

When you equip them, stock attachments help with aiming stability and overall movement speed; heavier-duty ones are all about stability and recoil control.

  • No Stock
  • Demo Fade Pro Stock
  • Tempus P80 Strike Stock
  • Corio Precio Factory
  • Ordnance Ravage-8
  • Demo Precision Elite Factory

Rear Grip

Rear Grip attachments serve two main purposes: buffing either Sprint to Fire speed or Flinch Resistance. Some also offer aim down sight speed, but their drawbacks include everything from losing recoil control to losing recoil control to aim walking speed.

  • Sakin ZX Grip
  • XTen Grip
  • D15 Grip
  • Phantom Grip
  • Support CP90 Grip


Magazines are relatively straightforward attachments, or at least the ones in the beta are. They increase the amount of ammunition you can carry, but your movement speed, sprint to fire speed, aim down sight speed, and reload speed will suffer as a result of the extra weight.

  • 45-Round Mag
  • 60-Round Mag


The amount of ammunition you use in your rifle affects a few things, whether it's wounding them or providing additional penetration. Some weapons will reduce their damage range and penetration in order to compensate for their other effects.

  • 5.56 Armor Piercing
  • 5.56 Frangible


Attachments to underbarrels aid in idle sway, recoil control, and general accuracy. Expect to lose some focus down sight and walking speed in most cases.

  • FSS Sharkfin 90
  • Forge-Tac Ripper 56
  • Lockgrip Precision-40
  • VX Pineapple Vert Grip
  • SPW 40mm


The Receiver is less a gadget than a hook. There are currently four additional models available that enhance the weapon's performance and stats.

  • 556 Icarus, a box magazine and LMG-style Receiver for sustained fire
  • FTAC Recon, a powerful, longer-range receiver that turns the M4 into a battle rifle
  • M16, a classic style of Receiver providing powerful three-round burst capability
  • FSS Hurricane, a shorter range and lower-power rounds made up for with enlarged ammo capacity and enhanced stability
