Weapon Breakdown - SOPMOD M4

The M4A1 shown here has been modified with the Special Operations Peculiar Modification (SOPMOD) accessory kit. The Rail Interface System, or RIS, allows the attachment of numerous aiming devices and accessories depending on the mission. This M4A1 has been modified with a Trijicon ACOG (Advanced Combat Optical Gunsight) 4 x 32 scope; on the handgrip is an AN/PEQ-2 Infrared Target Pointer/Illuminator/Aiming Laser (ITPIAL). The PEQ-2 emits a laser beam for precise aiming of the weapon. It may also be used for lasing target for the delivery of smart bombs. Finally, attached to the barrel is a Quick Attach/Detach (QAD) Sound Suppressor. With the suppressor attached, the muzzle blast, flash, and sound are significantly reduced.
