For more than 25 years, we know what you like about airsoft.
The RetroArms CNC trigger is designed for M4 / AR15 and SR-25 airsoft guns. Thanks to precise CNC machining, low weight and a design compliant with the TM standard, it is suitable for upgrading V2 and V2.5 gearboxes. The surface is protected by a 5 µm anodized finish available in several colour variants (0.005 mm). The newly designed trigger shape contributes to fast response when pulled. In addition to AEG gearboxes (standard and CNC variants), the trigger is also suitable for HPA systems that use TM-standard triggers. The trigger spring is not included; you can use the original spring or purchase a reinforced RetroArms version separately.
The trigger is made of EN AW 7075 aircraft-grade aluminium, offering high strength while maintaining low weight.
The precise design of the trigger is achieved by machining on a CNC machining centre.
The trigger is designed for standard AEG trigger contacts, ETU processor units and compatible HPA engine systems.
The trigger is designed according to the TM standard and is compatible with most trigger contacts without modifications. Some trigger contacts may require modification of the contact shuttle.
The aluminium component features a 5 µm protective anodized finish.
