PJ’s Steyr AUG

Hi all, I looked and searched for any vouches on this Sub, but didn't find anything vouching for PJ's AUG. so to make a long thing short, do they seem legit, do they do good work, and did they move decently quickly? I have a kit that's missing several key parts to include the receiver, and it seems he's not stocked and I'd like to finish out.

Edit: Thanks for the overwhelming positive responses about his reliability. I'll be buying a receiver and bolt from him here when he gets the one I need in stock
