EDgun R5M/Lelya 2.0 Aftermarket Mag Question

On my 6th shot shooting JSB .25 King Heavy Diabolos the aftermarket aluminum magazine pictured below popped halfway out of its slot at the breech. Before I was able to grasp what had occured, I saw something fly forward in my peripheral view. When I got a look at the mag from the front (before I removed it completely) I noticed the spring protruding. That’s when I realized that one of the tiny ball bearings dislodged and shot out into the grass. I tried using a magnet to find it but I was unable because I didn’t track where it landed when this first occurred. 


I searched and sifted through some posts and threads to see if someone had this issue, but found nothing of use. I can still use the mag, I’m just unable to store it beneath the picatinny rail with the others without a simple repair. It seems the plastic mags are more forgiving with using heavier pellets. I think I’ll stick to Kings in the aluminum mags, but I’d still like to find a replacement ball bearing (I guess that’s what it’s called). Does anyone know how I would go about finding a replacement for such a small part or where to find one?

Best I could think to do is measure with calipers, but I’m not sure which size to try to replace it with 4mm maybe. Any ideas?

After looking at their site, this must be a generation 1 magazine. I noticed that the Generation 2s have numbered chambers. If this is in fact an Eagle Vision mag it can never go hunting with me again. I took the other one (the good aluminum mag) hunting and it failed to cycle a couple of times in the woods when I needed to shoot. It’s going to stay home as a possible backup for target practice at best. The broken one isn’t worth fixing. If I figure it out, great. If not, so what.
