It’s really more of a shroud and it’s used by those who want to use short handguards along with longer barrels. It’s an aesthetic issue really. The down side to adding such extensions is that they prevent the use of a compensator. But, Strike Industries’ Cobra Series barrel extension overcomes this by removing the front cap. Then you can install any AR threaded compensator.
You can also apply the forthcoming S.I. FAT COMP which is specially designed with the same diameter as the Cobra barrel extension, allowing it to sit perfectly flush.
