It looks good to me.  Reliability will also depend upon the lower and style of mag and feed ramp, or lack thereof.

its a aero epc lower. i know the aero ba barrels have a poor feed cone. since i cant find anyone skilled enough to verify if the mag well is in spec and not the reason behind the misfeeds. i have to assume its the barrel and lack of a decent feed cone.

and yes i have contacted macon. but due to my employer it wont work out to send to him.

I have an 8.3" BA barrel in my AR-9 and it has run 100% without a single hiccup, but I am using Endomags which have a feed ramp built in.  You are correct that the Aero lower does seem to have more issues than any other system, but it isn't all the fault of the barrel.  I have seen many complaints with Glock mag systems from other manf's as well as Aero.  Not only do they look dorky, Glock mag guns are finicky.  Now I am sure some Glock mag AR-9 owners will dispute this, but I have been hanging around here for quite a few years and have seen it over and over.

I have a 8" BCA barrel that has proven to be very reliable.
It has a feed ramp cut in the barrel.  I also polished the whole feed area on my buffer.  Maybe it helps.  
I am running a mean arms adapter mag.
Colt style BCG from a YHM 9mm kit.
Just swapped it to a Gibbz side charging upper.

The only issue I've ever had with my ar9 was the BA 9mm barrel that had a nonexistent feedcone. Rudy fixed it with his magic. The mags weren't the issue. Looks are subjective.

That being said. My ar9 gets WAYYYY more attention when I bring all my toys to the range. People don't want to put it down. As for the "fun" factor, its also on the top of my list. Its also cool cause it uses the same mags/ammo as my EDC.

There's lot of cheap pcc stuff out there. I'm sure if you go cheap you'll have problems (just like any other weapon system).

Not sure if you're a cop or what this means, but the obvious answer here is to just buy a barrel from rudy. Dude is a wizard with this stuff.

Just posting what I have seen posted here over the past 15 years.  The skimpy feed cones on most factory barrels cause issues with Glock mags more than others.  Rudy has fixed a lot of issues for people.  I agree that my AR-9 is also the one that gets the most love at the range.  Easy shooting.  Just plain fun.

Any update. Interested as I need a 6” barrel.
5.5” barrel is just a little short for the hand guard I want to use.
