Thanks. I am a retired precision machinist; therefore, you can get technical.

If you screw any of these items onto your barrel you are basically replacing the material that has been machined away with a threaded collar which will in turn assist in resisting gas pressure at the crown area.
It would be interesting to know how these barrels were fired and what loads were used ie: hot loads or not, what type and size suppression was used etc? There are a lot of variables so to say that 5/8 24mm is less suitable for accuracy is not an entirely correct statement
