"Colt M4A1 SOPMOD Special operations forces can personalize their fully automatic M4A1s with a broad range of SOPMOD accessories.
Few weapons provide today's special "operators" with the tactical flexibility offered by the M16/M4 series' Special Operations Peculiar Modification (SOPMOD) hardware. Under the coordination of the SOPMOD Program Management Office at the Naval Surface Warfare Center in Crane, Ind., the SOPMOD is a kit concept designed to provide standardized, versatile weapons accessories to meet needs across special operations mission scenarios. Individual accessories are selected for the SOPMOD kit based on their contribution toward increasing operator survivability and lethality by enhanced weapon performance, target acquisition, signature suppression and fire control.The SOPMOD concept is based around the M4A1, the special operations variant of the Colt 5.56 x 45mm M4 Carbine, a versatile weapons system with a sliding buttstock and 14.5-in. barrel (the special operations A1 version is capable of fully automatic fire). When equipped with multiple accessory-mounting surfaces, the M4A1 SOPMOD allows the special operator to tailor his weapon to specific mission requirements."
