I got the PSA 7.5" ar with brace for $499. Fun as hell to shoot and reliable. For a CQB why not.

I’ve owned 6 psa ars. I usually build but the last few I’ve got have been great guns for me. Just got this one in yesterday and it’s nice.

I have the upper; bought a couple of years ago. It's fine but nothing special. Way overgassed. You would be paying about $200 here for the lower. I wouldn't buy it but that's my opinion.

If the carbine length is way overgassed, it makes me wonder about their pistol length gas uppers. I would like to build a super short AR-15 pistol for around $500, but perhaps it's just a bad idea. Maybe I should go the AR-9 route.

Get an adjustable gas block. They can be had for fairly cheap and will make a huge difference on overgassed rifles. Anything carbine or pistol length of mine gets an adjustable without question.

I don't think it's too bad of a deal for the lower because you get that brace no?

Ditto, the brace alone sells for over $100. Worse case you are getting a complete, assembled lower for less than $100.
