Not seen anything, it might be a bit niche for PTS, maybe, fingers crossed. From what I've seen generally there's (comparatively) not a ton of different types of mags out there for any of the normal AEGs even less so any of the GBB MP5s. Don't think there's a clone of the gun itself yet? That'll be part. RS wise the standard HKs mags are the only widely known style I'd say, with the old straight 30s a fair bit behind, then maybe a few know of the clear ETS ones.
