Selling my Well R4 (Tokyo Marui MP7 Clone) with an HPA conversion. This setup works flawlessly and is loaded with upgrades, making it a beast on the field. Here’s what’s included: PolarStar Jack installed for smooth, consistent performance. Bullgear upgraded hop-up and inner barrel for improved accuracy and range. 7 mags total: the original metal 50-round mag and six 100-round mags. Battery and charger included, so it’s ready to use. Feel free to message me with any questions or if you want more details. Thanks for checking it out!
