It would be interesting to know how many rounds have been fired through the barrel when the accuracy drops off and the barrel requires replacement.

Train 2 Win
It's simulated 300m at 25 meters and at actual range. Check FM3-22-9.
5-2. ZEROING PROCEDURES; a. The purpose of battlesight zeroing is to align the sights with the weapon's barrel given standard issue ammunition. When this is accomplished correctly, the point of aim and point of impact are the same at a given range such as 250 meters for the M16A1 and 300 meters for the M16A2/A3/A4 and M4-series weapons. This sight setting provides the highest hit probability for most combat targets with minimum adjustment to the aiming point.

You claim no one is doing it, so read for yourself.

Regarding the accuracy guarantee you can laugh as much as you want. Wilson Combat and Les Baer for instance do give such guarantee as well.
WC:
Les Baer:1 MOA or 2 MOA accuracy guarantees are based on the rifles
ability to place 3 consecutive shots (center to center) into the
guaranteed group size from a distance of 100 yards by at least
one of the following ammunition types. This is based on an
experienced shooter using a 10x or higher power optic, shoot
ing from a double sandbag benchrest on a calm day.
Federal Gold Metal 69gr HPBT Match
Federal Premium 55gr HPBT Match
Winchester 53gr HP
Hornady 55gr V-Max
Hornady 53gr HP Match
Black Hills 52gr BTHP Match
Black Hills 68gr BTHP Match
Black Hills 69gr HPBT Match
Remington 62gr HP Match
Handloads:
24.5gr AA2460, 69gr Sierra HPBT Match* or 68gr Hornady BTHP
24.5gr Win 748, 69gr Sierra HPBT Match or 68gr Hornady BTHP
26gr Win 748, 52gr Hornady BTHP Match*
For CQB training ammunition we recommend the Federal
American Eagle 55gr FMJ load.
*We have found these two loads to be extremely accurate in
our carbines.
Again, very doable under ideal conditions.Rifles are guaranteed to shoot 1" groups at 100 yards.

So my assumption that your comment was in any sort of context was false. If that comment about your wife wasn't meant to support the topic being discussed at the time (the 1 moa guarantee), why mention it out of the blue?
It can be BS, assuming again you're still talking about ASA barrels. The vast majority of barrels will never shoot consistently 1 moa, regardless of a rock solid 500 lb shooting vice, meticulously selected and QC'd ammo, no wind, 20x optics, a 1 lb trigger, etc. As shooting is randomness stacking on randomness, even a terrible load through a terrible barrel with a terrible shooter will, extremely rarely, print a touching group at significant range. But that does not make the barrel a 1 MOA barrel any more than hitting par once while golfing makes you a zero handicap golfer.Further I said that a 1" group at 100yds - under ideal conditions - is no BS!
Now if your "ideal conditions" does not include ASA barrels... What are you talking about? Just throwing statements out there without any sort of context? Yes, 1 MOA AR barrels and shooters exist. That's so obviously true that saying it out loud is a bit pointless, so I assumed you were logically using your responses to support your previous statements. If that was in error, I apologize for unintentionally carrying on a regular conversation.

"I never learned from a man who agreed with me." Robert A. Heinlein
10-shot, MOA-or-less groups from a reasonable platform (i.e., NOT a 500lb rest, but a smaller rest/bag set-up or a bipod on a bipod-mat would be valid) using match ammo shot by a human being through a magnified optic.
ASA barrels will not do this. I doubt they'd even do it in a giant, non-moving, mechanical rest.

Thank you for your input.
I'm not affiliated with ASA, they don't pay me money, I'm not getting free products, heck I'm not even a stocking dealer.
We argue about barrel specs or rather ASA's 1MOA guarantee that some of you say is BS. I doubt that since there are so many factors that can mess up the perfect shot. According to the specs posted by ASA the barrels should very well hold up to the general idea of producing 1MOA groups.
That's all!
Sorry if I hurt anyone's feelings. That was not my intend.
