It's a tech session for budding airsoft gunsmiths as Wyhaq documents how he build an airsoft Hi-Capa gas blowback pistol from scratch... "This video I show how to build a hi-capa from scratch, with no base replica. I use parts from AIP, Airsoft masterpeice, Edge, Guarder, and Knuckles GSM. This is part one, and we build completely the slide with all internal parts like blowback chamber, recoil system, and hopup chamber. We use an aluminum silver 2 tone staccato slide, and will be using a gunsmith bros advance frame or aluminum red anodized advanced frame."
