Valiant Airsoft shows you the upgrades he made to his Hi-Capa Gas Blowback Pistol to squeeze out more performance from it... "In this video I perform a slide change/disassembly and a hopup upgrade to my red speedqb/competition hi-capa, and walk through the parts I have inside as we go. I switch from the Dr. Black 901 slide to the LA Capa Void slide and upgrade my AIP Hopup to the new LA Capa TDC hopup."
