I figured HK probably has some beefier parts thrown in as well but I thought that capability was primarily a result of the gas piston system because you don't have to worry about the crazy overpressure of trying to fire completely underwater or with a partially blocked barrel being directed all the way back to your gas key/BCG/etc. The gas piston setups I'm familiar with usually vent the extra pressure at the gas block or gas tube once the piston has moved far enough to operate the bolt.

Not sure if that is correct, but that's what I was thinking.
