M16 Vietnam Hi-Cap Magazine 190rds – Tokyo Marui

The Tokyo Marui M16 Vietnam is a 190-round high-capacity magazine designed for M16/M4 series airsoft AEGs. It reproduces the distinctive short, straight magazine profile associated with early M16 rifles used during the Vietnam War, combining a classic military appearance with greater capacity than traditional short magazines. Its metal construction and winding mechanism make it suitable for both historical-style builds and compatible modern airsoft replicas.

Operation and compatibility

The high-capacity system holds up to 190 BBs, which are fed through an internal spring mechanism operated by the bottom winding wheel. Periodic winding is required during use to maintain consistent feeding.

The shorter magazine profile reduces bulk beneath the replica, making it particularly practical for DMR configurations and shooting from prone positions.

Compatibility with M4/M16 replicas from other manufacturers depends on magazine well tolerances and feeding system geometry. This magazine is not designed for GBB platforms.
