Retro Arms Anti-Wobble Pin for AR15/M4 - Black
The Retro Arms Anti-Wobble Pin is a CNC-machined three-piece receiver pin designed to reduce movement between the upper and lower receiver of compatible AR15 / M4 AEG replicas. Tightening the integrated Torx screw expands the split pin inside the receiver, creating a firmer and more stable connection than a conventional body pin.
The design is particularly useful in replicas where wear or manufacturing tolerances have created noticeable play between the upper and lower receiver. In addition to reducing wobble, the screw-secured construction helps prevent the pin from working itself loose during use.
Three-piece expanding design
The current generation Anti-Wobble Pin uses a three-piece split construction. When the Torx screw is tightened, the internal sections expand against the receiver opening and lock the pin firmly in place.
The adjustment should only be tightened enough to remove unwanted movement. Excessive tightening is unnecessary and may place additional stress on the receiver.
Compatibility
- Designed for AR15 / M4-style AEG receivers
- Suitable as a front receiver pin for most Tokyo Marui-spec AR15 / M4 receivers
- D-shaped head improves compatibility with common TM-spec front-pin locations
- Can also be used as a rear receiver pin with compatible Retro Arms CNC receivers
Receiver dimensions vary between airsoft manufacturers. Compatibility should therefore be checked before installation, particularly when using the pin with non-Tokyo Marui-spec receivers.
