I was wondering why the M4 barrels have the smaller portion towards the muzzle.
Sorry if this has been addressed here before, but I've only been around here for a couple of months.
Thanks in advance for any input.

It's for the ring that mounts the M203 grenade launcher.

Thanks, I thought that might be it, but wasn't sure.
