I'm considering a Surefire 5.56 can. Is there any real difference in performance between a 556RC and a 556SB can on a 16-inch barrel? Thanks.

From what I've read, the SB is designed with a slightly larger bore to reduce projectile baffle strikes by unstable ammo fired from barrels shorter than 10 inches or longer barrels firing frangeable ammo. Though I couldn't find it, the suppression is about the same between RC and SB.
