Retro Arms CNC Trigger for Arcturus M4, Black

The Retro Arms CNC Trigger for Arcturus M4 is a CNC-machined trigger from Czech manufacturer Retro Arms, made for Arcturus' M4 replicas. It has a curved blade in a black finish and replaces the factory trigger.

Arcturus AEGs are popular for their build quality and electronics, but the factory trigger is one of the parts many players want to tailor to their own style. A CNC-machined trigger gives tighter tolerances than cast parts and a more consistent trigger feel. The trigger is for Arcturus' M4/AR-15 platform – not their AK models.

Features of the trigger

Advantages of the Retro Arms Arcturus trigger:

• Made for Arcturus M4: Retro Arms has made the trigger specifically for Arcturus' M4 replicas, so you get a part designed for exactly that platform rather than a universal M4 trigger.
• CNC-machined: Machined to tight tolerances, so fit and break point are more consistent than with cast parts.
• Curved blade: The curved shape places the finger naturally and gives a familiar, comfortable trigger feel.
• Low weight: Approx. 5 g, so it doesn't affect the return of the trigger spring.
• 24-month warranty: Retro Arms manufactures in-house in the Czech Republic and gives a 24-month warranty.

Maintenance and safety

• The trigger fits Arcturus' M4 models – not the AK platform.
• Check that the trigger activates the contact or sensor correctly and returns freely before closing the gearbox.
• Always remove the battery and empty the magazine before opening the replica.
• Our workshop in Aulum, Denmark can fit the trigger for you.
