I'm a tier 83 operator who tends to build a rifle, take it to the range a few of times to sight it in and then not do much else with it. I may shoot one of my AR's five or six times a year. I have never fired a shot in anger or under any sort of extreme condition. My mag dumps usually consist of loading five shots and then shooting a group before checking the spotting scope. In other words, my opinion is worth absolutely nothing when it comes to AR-15s . . .
That said, my current main AR-15 sports a 16" Del-Ton midlength lightweight 1:9 twist barrel (Cromoly only, not chrome lined). I am 100 percent satisfied with this barrel. It's plenty accurate. I routinely manage 2 inch groups at 100 yards from the bench, using a 4x scope, even with factory ammo.
I also have another 16" midlength lightweight Del-Ton that was built using a Del-Ton kit. The only things about this gun that aren't Del-Ton are the Anderson lower and Magpul furniture. So, far, I've probably run a whopping 200 rounds through this gun. It ran fine. Accuracy seems OK, but I've only used open sights. Kit went together without a hitch.
So, for what my opinion and experience are worth (which is practically not at all), I'd say Del-Ton is definitely good to go. If you're like me and your AR's serve no meaningful or critical purpose and you subject them only to the most casual use possible, Del-Ton is as good as anything else on the market. Frankly, I have no doubt Del-Ton products would be up to much more challenging uses but I can't speak to that. Only you can decide how demanding your requirements are.
Just trying to keep it real, here, folks . . .
