SS109/M855 muzzle velocity
Wikipedia works with and needs external references to provide factual information like statements regarding barrel length and muzzle velocities. If several sources fundamentally disagree that must be mentioned. The Barrel Length Studies in 5.56mm NATO Weapons at http://www.sadefensejournal.com/wp/?p=1093 features an experiment using SS109/M855 ball cartridges that starts at 24 in barrel length and plots what happens when the barrel is cut to 5 in barrel length in 1 in increments. According to that source the muzzle velocity maxed out at 20 in barrel length using these cartridges. At http://www.dtic.mil/ndia/2010armament/WednesdayCumberlandPhilipDater.pdf this information is also provided in more detail by the US DEFENSE TECHNICAL INFORMATION CENTER.

At http://rifleshooter.com/2014/04/223-remington5-56-nato-velocity-versus-barrel-length-a-man-his-chop-box-and-his-friends-rifle/ is an article regarding (less professional) measurements with M193 55-grain ball, M855 ball and commercial .223 Remington ammunition fired from a factory Remington 700 varmint bolt action rifle chambered in a non mil spec 223 Remington with a 1:12 barrel. The 26 in barrel added 125 ft/s more muzzle velocity compared to the 20 in barrel with M193 55-grain ball and 183 ft/s more muzzle velocity compared to the 20 in barrel with M855 ball fired from a .223 Remington chambered bolt action rifle.

Wikipedia up to now has no data source that states muzzle velocities measurements at 24 in plus barrel length(s) for SS109/M855 ball cartridges fired from a 5.56 NATO chambered assault rifle. Can you provide such an open accessible internet reference? Please reference what muzzle velocity was measured by your source at 26 in barrel length using SS109/M855 ball cartridges in an assault rifle so it can be added to the article.--Francis Flinch (talk) 18:47, 16 November 2014 (UTC)
