$100 a mag...! And this toy would necessitate a few... nice carbine!
bullets, powder, primers, and case lots of CCI Blazer
Is there plans to get the PSA metalform 5/32 mags that are 40% the cost of the colt ?

I run the 10rd RRA 9mm pistol mags in my 9mm AR and they work great. I may pursue some baseplate extensions to make them a bit easier to grab/seat but otherwise I've no concerns with them. The 5rd pinned mags aren't of much use given their relatively low capacity.
