Spare parts and upgrades for gas-powered airsoft guns – mainly GBB pistols, but also GBBR rifles and NBB models. Here you will find both the small genuine parts that keep a pistol running after a breakage or a leak, and the parts that change how the gun shoots: hop-up buckings, inner barrels, valves, piston heads, springs, triggers and blowback housings.
The range is built around the most widespread platforms: Hi-Capa/1911, the G series (TM, WE, VFC/Umarex), AAP01, M&P, XDM and KSC/KWA models. WE and KJ Works supply genuine parts by part number, while Maple Leaf, Poseidon, Unicorn and Dynamic Precision cover hop-up, barrels and valves. For rebuilds and finish we have Action Army (including a large AAP01 programme), CowCow Technology, AIP, Guarder, MITA and TTI Airsoft.
What to look for
Platform and manufacturer: A Glock-type pistol from TM, WE and VFC/Umarex does not necessarily share parts. That is why hop-up chambers, nozzles and slides are listed for a specific model and make – check before you order. The WE G series follows the Glock numbering.
Hop-up and inner barrel: Hop-up buckings come in different hardnesses (e.g. 50, 60, 70 and 80 degrees), where softer buckings typically suit cool weather and low gas pressure. Inner barrels come in 6.01–6.04 mm and in lengths from around 80 to 180 mm to match the outer barrel.
Valves and gas routers: The magazine's outlet valve, fill valve and gas router are the classic wear parts behind leaks. High-flow valves (e.g. Maple Leaf MONSTER, Nine Ball NEO-R or Poseidon Turbo Valve) give more gas per shot and a stronger blowback.
Blowback and recoil: Piston head, nozzle, recoil spring, guide rod and hammer spring determine the cycle and reliability. Replace them together if you change gas or slide weight.
External parts: Triggers, magwells, magazine bases, thumb rests, sights and red dot mounts are mainly about ergonomics and setup – but always check model compatibility.
Who is it for
This category is for you who maintain or build on your own GBB pistol or GBBR, whether it is about stopping a leak or building a speedsoft or CQB setup. If you are unsure which part fits, the workshop in our shop in Aulum, Denmark can help identify it.
