This is probably splitting hairs, but I just want to know for the future. I've seen that Del-Ton, BCM, and a few others offer a "lightweight" barrel option. My understanding is that there is a difference between the "lightweight" profile and the "pencil" or "superlight" profiles. I know this guy is persona non grata around here right now, but do the other manufacturers follow this barrel profile criteria?
Barrel Profiles I went with a Bushmaster superlight barrel since they actually gave the dimensions and it seems to be the closest to the "featherweight" listed above. The difference between .625 and .55 on the barrel doesn't save that much in terms of ounces, but it makes a big difference in terms of inertia, so you can really get the barrel moved around more quickly. As a minimum, manufacturers really need to list rough barrel dimensions somewhere in the item details
