At 100 yds, Noveske guarantees sub MOA peformance on their 10" uppers. The reason for this is the same as why they are reliable.
The Krink flash suppressor creates a strong back pressure which is almost equal to the pressure from a 16" barrel producing enough force to complete the bolt cycle. The Krink also assists in the effeciency in which the gases are burned. In most 10" barrels with 5.56, unburned powder escapes the barrel before ignition and velocity is compomised. The krink causes some of the gases to recirculate before exiting due to it's shape, much like a suppressor will encourage gases to fold rearwards and cool before exiting the barrel.
The end result is a 10" barrel which peforms with muzzle velocity very near that of a 16" barrel.
Of course, the Noveske barrels aren't average barrels either, they're match grade heavy machine gun rated, extended feed ramps, custom matched to the Vltor upper and bolt face. The rifling is an improved polygonal 1X7 which also increases velocity and bullet stability.
It performs, seriously
