The KJ Works KP-05 is a gas blowback (GBB) pistol built on the Hi-Capa platform. Here you will find genuine spare parts for it – sold individually and named after the number on KJ Works' exploded diagram, so you can replace the exact part that is worn, broken or lost.
All parts come from KJ Works, from small springs and pins up to the larger mechanical parts. We also have a valve for the KP-05.
What to look for
Part number: Match the number on KJ Works' exploded diagram of the KP-05 with the product name. If in doubt, send us a photo of the part.
Gas or CO2 version: The KP-05 comes in both versions, and valves and magazine parts in particular are not the same. Check which version you have before you order.
Hi-Capa parts: Although the KP-05 is based on the Hi-Capa, Tokyo Marui upgrade parts do not always fit without adjustment.
