I didn't quite catch the mag size. I thought he said 30rd, but looking at Geissele's site, they're 20rd (and $115 each). That puts your 210rd loadout at 140rd. The gun is also a lot more expensive than one of their 5.56 Super-Duty MOD1's.
I guess I'm feeling it looks nice if someone else is paying, but I'm not convinced to buy one.
