The idea is mine, the execution I can take no credit for.  I've been working with Seb at double tap designs, that man is a 3D design genius!
 
	 
 
	Essentially, I run the APS CO2 mags in Glock builds, the ones with the hex screw brass bottom caps. 
 
	 
 
	I didn't like the design and lack of aftermarket mag bases on the original, this changes the mag base to be essentially like a standard TM.  
 
	 
 
	The CO2 brass end cap sits in the hole, you slide it on, then screw it in place with a hex wrench through a (smaller) hole in the bottom of the mag base.  A new bottom spring guide was needed too...
 
	 
 
	Final design is done, they're off to get printed in MJF by Protolabs.
