This is the VFC BCM 30-round Gas Magazine (Version 3), engineered specifically for VFC's M4 and HK416 series Gas Blowback (GBB) rifles. Constructed from durable metal, the magazine features a more refined design compared to its predecessors, with noticeably more rounded corners on its upper half for an improved aesthetic and feel.
It boasts a 30-round loading capacity and is designed for use with 6mm plastic BBs only. Ready to use straight out of the box, it is compatible with both Green Gas and Top Gas. The magazine is officially licensed by BCM, as evidenced by the engraved "BCM" marking, certifying its authentic quality.
A key upgrade in this Version 3 model is the inclusion of a new selector switch. This switch allows you to toggle between two practical modes: a last-round bolt hold open function, which locks the bolt back after the final BB is fired, and a dry-fire mode, which permits realistic blank firing without loading any BBs, ideal for safe handling and trigger practice.
For optimal loading efficiency, we recommend using a plastic BB loading tool or speed loader alongside this magazine. It stands as the perfect functional companion and upgrade for your VFC M4 or HK416 series GBB rifle.
