Over/Under Picatinny Glock Mag Holder

I wanted to be able to store more mags on my Chassis. The Meta Tactical Fore-grip and mag holder works great, but only holds 1 mag. 

I designed this to accept mags from the top or bottom. The mount is designed as a solid piece with only a pin for securing mount to rail. Everything is 3d printed.

Print on the side with supports for Pic section. I wanted the insides of the mag well to be ultra smooth so decided against printing the mount upright. 

The mount may wear over time. I wanted the mount to be replaceable rather than wearing through mags (it is a friction hold, there are no buttons or levers, just smack and yank those mags!)

if your mount stops holding the mags securely, just print another :D
