    Parts Fitting

    Upgrades and Downgrades should only be undertaken by experienced players, or Airsoft Technicians. Please note, changing any internal parts of a weapon voids its warranty unless done in-house by our staff. 

    Please ensure that when fitting parts the part purchased is the correct part, as once a part has been fitted we cannot accept return.

    We do know that players love to tinker, so we're here to give you help should you require it, and if needed you can get in touch with our workshop for more help!

    Unique Parts

    Please note that some parts may be unique to a specific brand of weapon. For example: Parts for an ASG M4A1 may not fit an ICS M4A1.

    Parts from the same brand typically have a high chance of fitting, though be warned, some replicas use unique parts, so please ensure the part will fit before you attempt to fit it.

    If you require help with fitting any parts feel free to get in touch with us via our Contact Us Page.
