10-Round, AICS Spec, PMAGS

Been done already, but they were never fully developed or otherwise put into production.

There are pics floating around here somewhere as LL had a couple of the prototypes for T&E a while back (like 2009-2010 IIRC). I'm pretty sure that they have been indefinitely placed on the back burner (or perhaps even cancelled outright). I think that they are visible in a video LL did of his 16" POF P-308 if memory serves, but its been a while like I said (couple years at least). You might try a search and see if they pop up.
 
I figured it's been attempted....I have horrible luck when it comes to ideas that are original.

I promise though, I did a search for AICS PMAG and only 19 posts came up. None were relevant...I even did it again and it doesn't even include this thread. ;)

I'd be interested in seeing the thread that Lowlight created if you come up with it.
