COWCOW Technology Tokyo Marui Hi Capa GBB Airsoft B01 Aluminum Dynamic Blowback Housing (BBU) - Blac

COWCOW Technology B01 CNC 7075 Aluminum Dynamic Blowback Housing is highly durable too and is designed for the Tokyo Marui Hi-Capa 5.1 GBB Pistol, but most importantly, it delivers a much faster blow back action due to lower inertia. Weight is the enemy of speed!
