Probably should be shipping to customers worldwide right now is the Modify-Tech PP-2000 CO2 and Gas Blowback SMG that was first revealed at the IWA Outdoor Classics 2019. Masaki Otsuka of Gunsmith Baton got the prototype to give a review in this video... "PP-2000 (Overseas name: PP-2K) CO2 & 134a Gas Gun 'Japan specification' prototype video. This is a trial of the prototype, so the trajectory and movement are for reference only. This is the PP-2000 Japanese version prototype video and it is different from the overseas full power specifications PP-2K of MODIFY."
