RetroArms CNC Split Wedge Body Pin for AR15
RetroArms CNC split wedge body pin is designed for M4 / AR15 airsoft receivers and addresses play that can develop between the upper and lower receiver. Compared with the previous design, the new generation uses a 3-piece construction, where the third component helps take up the clearance between the upper and lower receiver as the pin is tightened. The result is a more solid assembly with less movement between the receiver sections, which can be particularly useful on guns with larger manufacturing tolerances. Thanks to the D-profile head, the pin can be used as a front pin on most compatible M4 / AR15 receivers built to the Tokyo Marui standard, while on RetroArms CNC receivers it can also be used in the rear position. The individual parts are tightened together with a Torx screw, so installation does not require any complicated modification of the receiver. The pin is precisely CNC-machined and finished in black. Due to different manufacturing tolerances between brands, dimensional compatibility should be checked before installation in receivers from other manufacturers.
Key Features
3-Piece Wedge Construction
The new generation uses three interacting components that help take up clearance between the upper and lower receiver when tightened.
Tighter Receiver Fit
The wedge principle helps reduce unwanted movement between the upper and lower receiver, which is especially useful on M4 / AR15 replicas with larger manufacturing tolerances.
Front and Rear Use
The D-profile head allows the pin to be used as a front receiver pin on most compatible TM-standard receivers. On RetroArms CNC receivers, it can also be used as a rear pin.
Easy Tightening With a Torx Screw
Receiver play is adjusted by tightening the Torx screw. This allows the fit to be easily fine-tuned during assembly.
Precise CNC Machining
The pin is produced by CNC machining, allowing precise manufacture of the individual components and reliable operation of the wedge mechanism.

Frequently Asked Questions (FAQ)
What Is the Split Wedge Pin Used For?
Its main purpose is to take up play between the upper and lower receiver of an M4 / AR15 airsoft gun. Once the wedge mechanism is tightened, it helps reduce movement between the two receiver sections.
Can the Pin Be Used at Both the Front and Rear?
On RetroArms CNC receivers, it can be used at both the front and rear. Thanks to the D-profile head, it is also suitable as a front pin for most compatible M4 / AR15 receivers built to the Tokyo Marui standard.
Will It Fit Every Airsoft M4 / AR15?
It is designed for receivers based on the Tokyo Marui standard, but fit cannot be guaranteed with every receiver from other brands. Manufacturers use different dimensions and tolerances, so some guns may require fitment checks or minor adjustment.
How Does the Pin Remove Receiver Play?
After the pin is inserted, its individual components are drawn together by the Torx screw. The wedge mechanism then takes up clearance inside the pin hole and helps hold the upper and lower receiver more firmly together.
