Yes, the 7SAUMS have a heavier barrel. The slightly heavier barrels actually feel better balanced to me than the lighter barreled M7s. I don't know if it is the same contour, less flutes, as the M7 Predator's fluted barrel or not.
My .223 M7 CDL is just too muzzle light for me.
Anyone ever try hollowing out the CDL stock to lighten the buttstock?
