The 4UAD Sealant pen is a new perspective in Airsoft teching.
Apply a little bit of the 4UAD 4UANTUM sealant to the leaking area, assemble, let it cure for a day and it should be fine.
It's a high viscocity sealant (think grease), that can be applied to leaks in gas mags, sealing up any threads or small areas.
Admittedly, the best solution is still to replace the o-rings with better fitting ones, but it's not always an option, and that's where the 4UAD Sealant pen can be used. It's a good tool to have for a tech, and I've used it on a number of occasions.
Feel free to inquire on our various social media platforms about how to use it, or watch the Youtube videos for additional information.
