This MP5 HPA adapter represents the culmination of months of work to produce, from scratch, a shortened magazine for the Tokyo Marui GBB MP7. This leads to an ultra lightweight magazine setup, that is both more enjoyable and economical than buying the gas mags.

A donor mag is required for feed lips, exhaust valve, gas route and valve knocker.
