We know the APS UAR is hard to get hold of, has mag compatibility issues and can be difficult to upgrade.
To address this, we have developed an AEG M4 conversion kit. Specifically, the kit has been based around the Specna Arms SA-F09 (Polymer body, programmable burst mosfet). As we test it on other M4 models, we'll update the models that can be fitted. However, because the M4 sits in the back, we would recommend polymer models.
For anyone who already owns the MRK kit for the UAR, the kit is completely compatible with this new adapter and is secured using a handful of screws.
Kit Features:
- Ambidextrous forward mag release (above trigger)
- Mechanical linkage to trigger (n.b. the SA-F09 can be set to a hair trigger)
- Battery storage in stock
- Gap in bottom of stock section so you can run a HPA hose line through the AEG grip.
The kit will be released by the end of Jan 2026. Price TBC
