Read the article, gentlemen.
I did. And it didn't address what real benefit this would have for an underpowered round like a 5.56/.223. I guess for a really really poor shooter it could help but even an above average shooter should be able to shoot the effective range of a .223 with iron sights much less a scope. And a .223 round is not effective at all at ranges of 1000 meters or more. Shooting an M-16 or M-4 at those ranges is pretty much a waste of ammo.
