Frequently Asked Questions

Need To know more?

Do These Parts Fit Tokyo Marui Clones?

The parts in this collection are designed for genuine Tokyo Marui models. Some clones follow TM's design and will accept them, but fit isn't guaranteed, so check the compatibility listed on each product before buying.

What Does an NPAS Valve Do?

An NPAS is an adjustable valve fitted to the nozzle of many gas blowback rifles. It lets you fine-tune how much gas is used to fire the BB, so you can set your FPS to suit your site's limits without changing gas.

Will Upgrading My TM GBB Affect Its FPS?

Some parts, such as valves and nozzles, can change your FPS, while others mainly improve durability or cycling. Always chrono your gun after fitting new parts to make sure it remains within your site's limits.

Tokyo Marui Gas Blowback Parts

Tokyo Marui is one of Japan's best-known airsoft manufacturers, and its gas blowback pistols, rifles and shotguns are renowned for their reliability straight out of the box. Because they are built to meet Japan's strict power limits, many UK players choose to upgrade them for extra performance and durability, and this collection brings together the parts to do just that.

Rifle and shotgun parts

For the MP7A1, we carry steel recoil rods, back plates and threaded outer barrels from Pro-Arms, plus adjustable NPAS valves from Jaeger Precision. Saiga-12K owners will find reinforced nozzle control arms, CNC loading nozzles and uprated springs, while MWS and AKX parts include bolt carriers, piston heads and gas fill valves. For a dedicated MWS selection, visit our Tokyo Marui MWS parts and accessories.

Pistol parts

Upgrade your TM pistol with stainless steel hammer sets, low-friction blowback housings and enhanced piston heads from TTI and Cow Cow. Hi-Capa owners should also browse our dedicated Hi-Capa upgrades, and you'll find more in our pistol spare parts.

Fitting and compatibility

Upgrading one area can affect reliability elsewhere, so we recommend changing parts in matched sets where possible and always checking your FPS against your site's limits after any work. Shop the full Tokyo Marui range, or see our gas blowback rifle parts for other brands.
