SRU, busy thinking of new kits for airsoft, got something that Hi-Capa GBB users would welcome as an option kit, a PDW Kit. This kit is designed for the 5.1 and 4.3 Hi-Capa GBB Pistols from Tokyo Marui, KJ Works, WE Airsoft, and AW Custom. This allows you to have a more stable platform with your pistol especially for close quarters airsoft battles.
