An upgrade over most cages on the market that are usually made from soft aluminium or pot metal. This CNC machined alternative from RetroArms can withstand far more abuse, twist and strain especially from upgraded motors. A recommended component for those Airsofters who are building custom high rate of fire or high FPS builds. Screws are also included and just like all RetroArms components, you are not getting cheap quality screws.
- Great upgrade part

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!
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.
