Hi-Capa Spilt Hpa mag

I have always looked at M4 hi-capa adapters and wanted the quick mag change, without unplugging and replugging the HPA line on my Hi-Capa, and one day, I had a thought, is there enough space to split the mag in two?
turns out there is!
I split the mag almost down the center, so there is now an HPA side and a BB side, the HPA side is pinned in place, at the correct height. the BB side resembles an AEP mag, and uses the original mag release (one of my biggest gripes about m4 adapters other than the look)
The only modification of the original pistol is the pinhole in the handguard, (if I didn't miss the first time lol) it would almost not be noticeable
It's printed in ABS, and acetone smoothed for pressure tightness, it holds 80 PSI without leaks at all.
The mag works wonderfully and cycles the pistol just like a normal HPA mag, but I have yet to field test it.

The HPA side needs to be pinned in place in the mag well, measure carefully and drill the hole, if the hole if off, it might be too tight to cycle, or too loose and leak too much air and not cycle properly

Updated for fully printed bb-feed lips! no more cutting an original and filling it down!
