Muzzle: Lockshot KT85

The Lockshot KT85 muzzle attachment is recommended for the ISO 45. It helps to reduce the vertical recoil, making it easier to control the weapon and stay on target.

Laser: Accu-Shot 5mW Laser

The Accu-Shot 5mW Laser improves the aim down sights (ADS) speed of the ISO 45. With faster ADS speed, you can quickly acquire targets and react faster in close-quarters engagements. If you prefer not to have a visible laser, you can choose the 1mW Quick Fire Laser as an alternative.

Stock: Demo Fade Tac

The Demo Fade Tac stock attachment is a great choice for improving weapon handling. It increases Aim Walking Speed and Sprint Speed, allowing you to maneuver swiftly around the map. In MW2, where strafe speeds are relatively slower, the improved Aim Walking Speed is especially beneficial.

Ammunition: .45 Auto Armor Piercing

The .45 Auto Armor Piercing ammunition gives the ISO 45 the ability to shoot through certain surfaces. This can be advantageous when engaging enemies who take cover behind thin walls or objects. However, if you don’t prioritize penetration, you can opt for a close-range optic or consider using the 12 Round Mag attachment, which converts the ISO 45 into a semi-automatic weapon.

Rear Grip: A30 Stout

The A30 Stout rear grip attachment is another important addition to reduce the vertical recoil of the ISO 45. By combining it with the Lockshot KT85 muzzle, you can further enhance your control over the weapon and maintain accuracy during sustained firefights.

Best ISO 45 MW2 Class: Perks & Equipment

Base Perk 1: Double Time

The Double Time is an excellent choice for the first Base Perk slot. It doubles the duration of Tactical Sprint, allowing you to sprint faster and for a longer period. This perk is particularly useful when using a close-range weapon like the ISO 45, as you’ll be constantly on the move and maneuvering around the map.

Base Perk 2: Tracker

The Tracker is a valuable perk that reveals the footprints of nearby enemies. It helps you track and locate enemies more effectively, making it easier to hunt them down. This perk is especially beneficial for aggressive players who actively seek engagements and push forward.

Bonus Perk: Cold-Blooded

The Cold-Blooded is a fantastic bonus perk choice as it prevents you from appearing or being identified by enemy killstreaks. This perk is essential for maintaining your stealth and avoiding detection, ensuring that enemy killstreaks like VTOLs or Chopper Gunners don’t disrupt your gameplay.

Ultimate Perk: Ghost

The Ghost is an ultimate perk that keeps you off enemy UAVs. It’s crucial for aggressive playstyles, as it allows you to move around the map undetected. By staying off the radar, you can surprise your opponents and catch them off guard, gaining a significant advantage in engagements.

Lethal: Frag Grenade

The Frag Grenade is a lethal equipment choice that can deal significant damage to enemies within its blast radius. It’s particularly effective when thrown into areas with multiple enemies or used to flush out opponents from cover.

Tactical: Flash Grenade

The Flash Grenade is a tactical equipment choice that blinds and disorients enemies upon detonation. It provides a window of opportunity to take down enemies who are temporarily unable to defend themselves. Proper utilization of the Flash Grenade can lead to free kills and turn the tide of a firefight in your favor.


ISO 45 in Modern Warfare 2 Season 4 is a powerful submachine gun that excels in close to medium-range engagements. With its high fire rate and impressive stopping power, it has quickly become a favorite among players.

By equipping the recommended loadout attachments, including the Lockshot KT85 muzzle, Accu-Shot 5mW Laser, Demo Fade Tac stock, .45 Auto Armor Piercing ammunition, and A30 Stout rear grip, you can enhance the weapon’s control, handling, and penetration capabilities.
