You know whats funny Frank, One of the guys who shoots aero is the same dude who was told by the owner of DD that his 6 creed barrels last 5K rounds. Back when DD was paying PRS $50K a year to be the "official rifle of the PRS", despite no one actually shooting them in comps. I think he offered to send him a gun to test, not sure if it ever happened. He was actually mentioned on one of your podcasts if you remember the cameo thing from a year or two ago where they kicked someone out.
The Aero guns that were fucking up were full production variants. I think they had already sold something over 1000 guns at the time. I shot a few different ones before the match and was actually thinking of buying a few (we could get everything for 50% off) as a buckup hunting rig and a loaner match gun. The exact words out of homeboys mouth were "dont buy this shit, they need to fix alot of things before its worth spending money on".
When i first picked up his solus, I was super impressed how smooth it felt. Then he told me spent about 20 hours working the action and hand polishing the internals to get the grit out.
I think if you stick with full sized cases like 308 and 6/6.5C the issues aren't as apparent, but when you try to stick a BR sized barrel on there, especially with AW mags, feeding issues become a big problem. This was like 2 years ago, so maybe they redesigned some stuff, but I haven't kept up.
For what they cost, I would spend a little more on a Origin or ARC which IMO, is a much better action, will hold its value better and you will get much better customer service if you do have an issue.
