What's the weight difference between a M4, Socom, and M10 barrel?

I see those offerings in 16" length on the CMMG site. And do any of those have an accuracy advantage over the other?

The difference in weight between a M4 barrel and a SOCOM barrel 4oz. I haven't weighed a M10 16" CMMG bbl, I do have one at work but I think it's too heavy for my digital scale. Accuracy in theory of the three probably goes to the SOCOM and M10, all are chrome lined carbine barrels not 1/2 MOA guns so I wouldn't feel underarmed with any of them.
