Best ISO Hemlock loadout and attachments in MW3

• Barrel: Fielder-T50
• Laser: FSS OLE-V Laser
• Ammunition: .300 BLK Armor Piercing
• Rear Grip: XTEN Grip
• Optic: Cronen Mini Pro

To start things off, the Fielder-T50 barrel will provide you with an improved damage range, recoil control and bullet velocity, giving you an enhanced range as well as a boost to hip fire accuracy which always comes in handy for close-quarters combat. The FSS OLE-V Laser will provide an increased ADS speed, Sprint-to-Fire speed and improve the ISO Hemlock’s overall stats. 

For Ammunition, we suggest going with the .300 BLK Armor Piercing as it can penetrate enemies and vehicles after extended shots. With the  XTEN Grip, you can add further ADS and Sprint-to-Fire speeds to your build to increase the weapon’s mobility and handling. Lastly, the Cronen Mini Pro Optic will give you great aiming with the ISO Hemlock, increasing your chances of getting headshots. 

Best ISO Hemlock perks and equipment

• Vest: Overkill Vest, 
• Gloves: Marksman Gloves
• Boots: Covert Sneakers
• Gear: Threat Identification System
• Tactical: Stun Grenade
• Lethal: Proximity Mine

The Overkill Vest will allow you to reload while sprinting, giving you an increased boost to your weapon swap speed. As for Gloves, the Marksman Gloves will reduce your sway and flinch while aiming down sight. This will improve the ISO Hemlock’s handling while the Covert Sneakers will reduce the noise from your footsteps, increasing your chances of getting stealth kills and executing finishing moves. 

For your Gear, we suggest using the Threat Identification System to increase your ADS speed which also lets you pinpoint enemy locations while ADS. As for Lethal and Tactical, the Stun Grenade is a fine choice of equipment that can slow enemies down, giving you an opener to finish them off. Proximity Mines can set deadly traps for enemies if they get too close to your location.
