DPMS lower that uses G3 mags???

[SWshooter]

I was at show this weekend and picked up some mags for my HK 91. They were only $5 apiece. I found two other places online that had them for $3 apiece. I wonder if anyone makes a lower that uses G3 mags and is compatible with a DPMS upper. You could save enough on a dozen mags to pay for the lower, with DPMS wanting $50 a pop for mags. It would also be really handy if the HK and LR-308 could use the same mags.

I really like the idea of the G3 mags, especially since I own quite a few already
