In this video the guy worked the bolt after removing the rifle from the water and before firing the first shot. Perhaps that was enough to make it function without failure.
Or perhaps this DI wasn't rigged to blow. Which is a rumor I've heard about the one in the HK movie.
Semi true; the video is an internal HK marketing video. Water in the gas tube will cause the tube to rupture but they purposely trapped water in the tube and forced a failure.
To ensure that your gun will function after being in the water.
Step 1) pull bolt back 1/2"
Step 2) Let go of bolt handle
....and that's about it. Just let the water drain out of the tube and you're fine.

I can't speak to the authenticity of the video; I just thought it was interesting. I do know that the design of the HK416 takes these adverse operating conditions into effect; in the second video they reference 'strategically-placed' drainage holes in the buffer and housing. I didn't see the bolt or handle operated in the second video, though (I seem to recall a similar test in Future Weapons but couldn't find the video).
Very enlightening Blaxsun. I wonder if the civi versions have the same drainage holes? I have an MR-308. Will have to take a closer look.
Thanks. I'll remember that for my next covert scuba beach assault.To ensure that your gun will function after being in the water.
