A modified M4A1 geared specifically for special forces operators. The SOPMOD accessories feature an integrated dot-sight and a high-quality silencer with reduced damage reduction.
  — Item Description 

The M4A1 SOPMOD (Special Operations Peculiar MODification) is an NX Rare variant of the M4A1 family.

It was added in the 4-29-09 Patch and can be obtained from certain Supply Crates. After the Fusion: Restore update, it became customizable through the Gun Emporium.


The SOPMOD has a unique desert camouflage paint job with a matching Suppressor and iTech Reflex Sight. These modifications cannot be removed or changed, so only the magazine may be modified.

The integrated suppressor gives the SOPMOD a unique firing sound and does not reduce damage output. The ITech Reflex Sight may limit this weapon's long range combat capabilities due to the lack of optical magnification.
