Frequently Asked Questions

Need To know more?

Will Pro-Arms MP7 Parts Fit Other MP7s?

Pro-Arms MP7 parts are designed for the Tokyo Marui MP7A1 GBB. Some are listed for the TM MP7 GBB series only, so always check the compatibility on each listing before ordering parts for other brands.

What Do 130% Springs Do?

A 130% spring is stronger than the factory spring it replaces. Uprated recoil and nozzle springs can improve cycling and feeding, especially when running more powerful gas, but may change how your gun feels and performs. Chrono your gun after fitting new parts.

What Do the Part Numbers Mean?

Codes such as MGG1-15 refer to the original Tokyo Marui part that the Pro-Arms component replaces. Matching the code to your gun's parts diagram helps you pick exactly the right upgrade.
