I was waitlisted and received one from Marstar about 6 months ago. I really really like it. At first I didn't want to keep it, it came as a surprise after returning from Hawaii for vacation, there was a package delivered for me containing a Norc CQ-a. I wasn't prepared to have bought this rifle at the time and nothing was emailed to me before sending/transferring it, but I couldn't send it back.
The price point plus the fact that it really is pretty nicely put together made it too compelling. Well that and I have always wanted to own an AR. The rifle delivered from Marstar had absolutely no problems and nothing was missing, scratched or broken.
I would easily recommend this rifle to anyone wanting an AR. There is only ONE caveat, and it was mentioned before. *DO NOT* buy this rifle and think you can use the shipped mags. They are ABSOLUTE GARBAGE. Both of mine would double feed or jam with one round's bullet stuffed down into the front of the magazine. The spring/plate feeding the rounds in the stock mags are such crap they shouldn't even ship them.
So, you NEED TO, not optional, buy nice mags when you get this gun. Personally, I went for a black 5/30 Magpul PMAG for some looks, and some LAR-15 10 rounders, for obvious reasons. Do that and you're golden. Everything else after that is pimping/customizing your new AR.
NOTE: if anyone knows, I noticed that Marstar is now sold out of the CQ-a. I'm just curious if they are getting more. Is anyone else bringing these rifles in in any significant quantities moving forward? Are they hard to get now?
