What are the advantages/disadvantages related to gas block position on the long handguard - short barrel AR-15 uppers. BM places the block on their Dissipator in the typical CAR position back under the guard. Most others, including DPMS (I think) place the block in the forward position.
I'm not sure there's an advantage to one design over the other, to be honest. We have to "tweek" them a bit more before they ship, but once that's done, they seem to be just as reliable as the other way.
