Heavy Metal Jacket Airsoft has been featuring gas blowbacks from VFC and in this video, it is about the VFC Colt XM16E1 GBB. This officially licensed Colt M16 gas airsoft rifle boasts the authentic size and markings of the experimental, pre-M16A1 model. While lightweight despite its 20-inch barrel, it features period-accurate details like an M16A1 handguard, steel flash hider, and Colt markings, making it a true collector's item for history buffs and airsoft enthusiasts alike.
