Hell, I'd be up for that, brother!
I have one, that came with the upper. They state it's a 30-round mag, but I've only ever been able to get 18 rounds into it - it gets tough! Since it's a single stack, and it's .45ACP, it's a pretty damn long magazine. It's only purpose is so you can run the upper on a standard lower, without using a magblock. I might buy one more, maybe, but it's kinda pointless since it's on the CNC Guns lower now.
I am going to contact them on Monday, and buy up all their .45 hard parts, though. Ejector springs, bolt components, etc.
