Genuine Colt parts and mil spec components!
The M4A1 Block II is a U.S. military designation for an upgraded version of the standard M4A1 carbine, commonly associated with SOCOM (Special Operations Command). It’s part of the Block II SOPMOD (Special Operations Peculiar MODification) kit, which adds modular enhancements to the base weapon, improving its performance and versatility for special operations forces.
Believe us, finding and sourcing many of these parts was HARD, but we managed to look in every nook and cranny and come up with a package that we feel can suite everyone’s needs, whether it be for budget or for authenticity. Nonetheless, be aware that these rifles are MADE TO ORDER and sometimes have long lead times depending on parts availability. We always recommend that you call or contact us to ensure that we fill your needs.
