Best Modern Warfare 2 MX9 attachments

The gunsmith in Modern Warfare 2 contains a huge range of attachments allowing players to gear any gun to suit their style of play. Here's an unbeatable combination to use:

  • Muzzle: FTAC Castle Comp
  • Barrel: 508mm Rear Guard
  • Laser: VLK LZR 7MW
  • Optic: SZ Lonewolf Optic
  • Comb: FTAC C11 Riser

This set of attachments includes numerous improvements. The combination of FTAC Castle Comp and Rear Guard barrel reduces horizontal and vertical recoil alongside improving damage range. Elsewhere, the VLK LZR and FTAC C11 Riser join forces for a significant reduction in ADS speed and sprint-to-fire time resulting in incredibly fast reaction times.

Although it may not have the power to dominate long-distance battles, the MX9 is more than capable of excelling in mid-range combat and close-quarters engagements.
